METHODS OF THE INVENTION

The present invention includes methods of analyzing samples from thenose for the detection of biological substances. In particular, nasalsecretion or nasal mucus is collected and analyzed for biologicalsubstances. The results of this analysis are then suitable for use indiagnosis, prognosis, and determination of suitability of therapeuticinterventions. The techniques of the present invention allow fordetection of biological substances that are typically not considered tobe present in the nasal area, but are known to be present in otherbiological fluids such as blood, serum, plasma, etc. Use of nasalspecimens provides a minimally invasive manner of obtaining biologicalsamples for analysis. Also, the techniques are used to detect substancesthat are not present in other biological fluids such as blood, serum,plasma, etc., but have been now detected in the nasal area.

The term “biological substance” as used herein, and its grammaticalequivalents, includes cells and their extra-cellular and intra-cellularconstituents. For example, biological substances include pathogens,metabolites, DNA, RNA, lipids, proteins, carbohydrates, receptors,enzymes, hormones, growth factors, growth inhibitory factors, cells,organs, tissues, portions of cells, tissues, or organs, subcellularorganelles, chemically reactive molecules like H⁺, superoxides, ATP,citric acid, protein albumin, as well as combinations or aggregaterepresentations of these types of biological variables. In addition,biological substances can include therapeutic agents such asmethotrexate, steroids, non-steroidal anti-inflammatory drugs, solubleTNF-alpha receptor, TNF-alpha antibody, and interleukin-1 receptorantagonists.

A first aspect of the present invention is a method of detecting abiological substance in a nasal specimen, wherein the biologicalsubstance is not related to a respiratory disease caused by a pathogen.Respiratory diseases caused by pathogens include upper respiratory tractviral infection, upper respiratory tract bacterial infection, bacterialsinusitis, and whooping cough. However, in some embodiments, the methodsof the present invention are suitable for detection of substancesrelated to respiratory diseases that are not caused by pathogens, suchas allergic rhinitis, asthma, and chronic obstructive pulmonary disease.It is understood that although some of these diseases are not caused bypathogens, they can be triggered or worsened by pathogens.

A second aspect of the invention is a method of diagnosing a disease byanalyzing a nasal specimen for a biological substance that is notrelated to a respiratory disease. The results of this analysis can thenbe used for diagnosis, prognosis, and determination of suitability oftherapeutic interventions.

The biological substances that can be detected by the methods of thepresent invention include, but are not limited to, insulin, insulinreceptors, leptin, agouti-related protein, ghrelin, glucose, caspases,adenylyl cyclases, carbonic anhydrases, TNF α, TNFR I, TNFR II, TRAIL,IL3, endostatin, erythropoetin, bone morphogenic protein, brain derivedneurotrophic factor, ciliary neurotrophic factor, granulocyte macrophagegrowth factor, hepatocyte growth factor, platelet derived growth factor,carbonic anhydrase VI, cAMP, cGMP, nitric oxide, insulin like growthfactor, and endoglin.

One embodiment of the invention is the detection of substances relatedto glucose metabolism such as insulin and insulin receptors. Thedetection of insulin, insulin receptors, and glucose is used in thediagnosis insulin resistance related conditions, such as diabetes. Useof nasal specimens for the detection of glucose and insulin provides aminimally invasive technique for diagnosis of diabetes and managingdiabetes care, in contrast to the invasive techniques such asvenipucture.

Another embodiment of the invention is the detection of TNFα in nasalspecimens. Elevated levels of TNFα have been shown to play a role indiverse disease processes. TNFα in nasal mucus was found to be about 30times higher than in saliva. The concentration of TNFα in nasalspecimens, thus, can be reflective of underlying disease processes. Thisdetection is used in the diagnosis of various cancers and inflammatorydiseases. Also, TNFα level monitoring in nasal specimens can be used tomonitor the efficacy of cancer and inflammatory disease therapeutics.Further, nasal administration of anti-TNFα drugs provides a means fortreatment of diseases in which TNFα plays a role. Also, levels of TNFαin nasal specimens can be used to study apoptosis.

Yet another embodiment of the invention is the detection of leptin,ghrelin and agouti-related protein in nasal specimens. Also, the methodsinclude the administration of substances that modulate leptin, ghrelinand agouti-related protein for the control of appetite and treatment ofobesity and anorexia. Nasal administration of leptin can inhibitappetite and nasal administration of agouti-related protein canstimulate appetite. Antibodies to leptin, ghrelin and agouti-relatedprotein can be administered intranasally to modulate appetite. Thismodulation includes control and/or stimulation.

In some embodiments, the methods of the present invention includedetecting cAMP and cGMP in nasal specimens. Comparison of themeasurement of cAMP and cGMP in normal subjects with patients with tasteand smell loss indicated that patients with taste and smell loss haddecreased levels of cAMP in their nasal mucus. Hence, cAMP in nasalmucus can be an index of smell loss. The detection of cAMP and cGMP inthe nasal mucus provides a non-invasive method for the detection oftaste and smell loss in a subject.

A third aspect of the invention is a method of treating a diseasewherein the treatment is based on the diagnosis of the disease byanalyzing a nasal specimen for a biological substance that is notrelated to a respiratory disease. Preferably, following the diagnosis, atherapeutic is administered which modulates the biological specimen. Insome embodiments, the treatment includes nasal administration ofbiological substances, such as, by way of example only, leptin, ghrelin,agouti-related protein, TNFα, insulin, or homones. In some embodiments,the treatment includes nasal administration of therapeutic thatmodulates the identified biological substances.

In one embodiment for treating diabetes and/or insulin resistance,following detection of insulin, insulin receptor and/or glucose, a drugthat modulates the insulin, insulin receptor and/or glucose isadministered. Preferably, this administration is via nose. The drug caninclude antidiabetic drugs, including insulin. In one embodiment fortreating cancer, following detection of TNFα, p53 or mutated p53, a drugthat modulates the TNFα, p53 or mutated p53 is administered. Preferably,this administration is via nose. The drug can include anticancer drugs.In one embodiment for treating leprosy, following detection ofantibodies against mycobacterium leprae, an antibiotic drug isadministered. Preferably, this administration is via nose. In oneembodiment for treating hepatitis, including hepatitis A, B, C, D, E andG, following detection of antibodies against hepatitis causing-virus, adrug, such as, by way of example only, interferon is administered.Preferably, this administration is via nose. In one embodiment fortreating obesity, following detection of leptin or agouti-relatedprotein, a drug that modulates the leptin or agouti-related protein isadministered. Preferably, this administration is via nose. The drug caninclude anti-agouti-related protein or leptin. In one embodiment fortreating anorexia, following detection of leptin or agouti-relatedprotein, a drug that modulates the leptin or agouti-related protein isadministered. Preferably, this administration is via nose. The drug caninclude anti-leptin or agouti-related protein. In one embodiment fortreating smell loss or taste loss, following detection of TNFα, CA VI,or TRAIL, a drug that modulates the TNFα, CA VI, or TRAIL isadministered. Preferably, this administration is via nose. The drug caninclude theophylline or other drugs known in the art. In one embodimentfor treating flu, following detection of flu causing pathogen orantibodies against flu causing pathogen, a drug that modulates theinfection is administered. Preferably, this administration is via nose.The drug can include antibiotics or other drugs known in the art.

The biological substances in the body interact with the brain via afeedback mechanism. The biological substances present in the nose aresecreted by glands that are controlled by a brain function and via thefeedback mechanism, these biological substances after secretion, in turnaffect the brain function. The nasal administration of the biologicalsubstance after diagnosing the disease by detecting the biologicalsubstance in the nasal secretion may be reflective of this feedbackmechanism.

In some embodiments, the treatment includes transcranial magneticstimulation (TCMS). TCMS or rTCMS (repetitive TCMS) can induce secretionof biological substances in the body, thereby inducing clinical changes.The patients suffering from loss of taste and/or smell (hypogeusiaand/or hyposmia, respectively) when treated with rTCMS, showedimprovement in their sensory acuity and decrease in their sensorydistortions. Some biological substances in these patients, such as, CAI, II and VI, zinc, and copper were found to be significantly higher inblood plasma, erythrocytes and saliva after treatment with TCMS. Theincrease of the biological substances in the body after TCMS indicatesthat TCMS induces biochemical changes in the body and can be used totreat various diseases including clinical abnormalities of sensoryfunction and neurological disorders.

The methods of the present invention disclosed herein include methodsfor detecting, diagnosing, and treating a disease in a subject, byanalyzing one or more biological substances in nasal tissue orsecretion. The steps of the methods of the present invention aredepicted in FIG. 1. Without limiting the scope of the present invention,the steps can be performed independent of each other or one after theother. One or more steps may be skipped in the methods of the presentinvention. A sample of nasal secretion is collected from a subject atstep 101. One or more biological substances in the specimen is detected,measured and/or analyzed at step 102 by detection techniques known inthe art, such as, PCR, mass spectrometry, protein assays etc. By way ofexample only some of the detection techniques are disclosed herein. Adisease is diagnosed at step 103 based on the detection, measurementand/or analysis of the biological substance. A decision regardingtreatment of the disease is made at step 104, the treatment decisionbeing made based on the diagnosis.

The identification of the biological substances may involve one or morecomparisons with reference specimens. The reference specimen may beobtained from the same subject or from a different subject who is eithernot affected with the disease or is a patient. The reference specimencould be obtained from one subject, multiple subjects or besynthetically generated. The identification may also involve thecomparison of the identification data with the databases to identify thebiological substance.

The steps of the methods of the present invention are provided herein.Without limiting the scope of the present invention, other techniquesfor collection of sample, detection of the biological substances anddiagnosis of the disease are known in the art and are within the scopeof the present invention.

Sample Collection

In the sample collection step, specimens from the nasal area arecollected for analysis. In some embodiments of the invention, a sampleof nasal secretions is collected directly from the nose into acollection tube or device. In other embodiments of the invention, asample of nasal secretion is collected on a sample collection device bypassing it into the nostril of a patient. The device may be insertedsequentially into each nostril of the patient and advanced parallel tothe hard palate with slow rotation. The device is then typicallytransferred to a transport tube, such as a glass or plastic test tube.The transport tube may include a suitable volume of a sterile mediumsuch as ethanol or the like.

Suitable sample collection devices are well known to those skilled inthe art. Preferably, a sample collection device can be a swab, a woodenspatula, bibulous materials such as a cotton ball, filter, or gauze pad,an absorbent-tipped applicator, capillary tube, and a pipette.Preferably, a swab can be used as a sample collection device, and thesample processing element comprises a swab holder or a swab processinginsert. The swab holder or swab processing insert can be tapered orangled to allow a single sample processing element to accommodate alltypes of swabs by allowing swabs with different amounts of fiber, orthat are wound to different levels of tightness, to be held securelywithin the holder or insert. Most preferably, the swab holder or swabprocessing insert securely holds the swab to provide stability.

In some instances, samples may be collected from individuals repeatedlyover a longitudinal period of time (e.g., once a day, once a week, oncea month, biannually or annually). Obtaining numerous samples from anindividual over a period of time can be used to verify results fromearlier detections and/or to identify an alteration as a result of, forexample, drug treatment. Samples can be obtained from humans ornon-humans. Preferably, samples are obtained from humans.

Analysis

In the present invention, a specimen of nasal mucus, secretion, ortissue is collected and analyzed using one or more analytical techniquesincluding enzymatic technique, ELISA, fluorometric technique, massspectrography, HPLC, GLC, PCR, and other similar techniques. The presentinvention also includes methods of diagnosing a disease by analyzingnucleic acids in a nasal specimen by nucleic acid detection methods suchas, but are not limited to polymerase chain reaction (PCR), ligase chainreaction (LCR), strand displacement amplification (SDA), self-sustainedsequence replication (3SR), array based test, and TAQMAN. A number oftemplate dependent processes are available to amplify the targetsequences of interest present in a sample. One of the best knownamplification methods is the polymerase chain reaction (PCR) which isdescribed in detail in U.S. Pat. Nos. 4,683,195, 4,683,202 and4,800,159.

Polymerase Chain Reaction (PCR)

The polymerase chain reaction (PCR) is a process for amplifying one ormore desired specific nucleic acid sequences found in a nucleic acid.Because large amounts of a specific sequence may be produced by thisprocess, it is used for improving the efficiency of cloning DNA ormessenger RNA and for amplifying a target sequence to facilitatedetection thereof.

PCR involves a chain reaction for producing, in exponential quantitiesrelative to the number of reaction steps involved, at least one specificnucleic acid sequence given (a) that the ends of the required sequenceare known in sufficient detail that oligonucleotides can be synthesizedwhich will hybridize to them, and (b) that a small amount of thesequence is available to initiate the chain reaction. The product of thechain reaction would be a discrete nucleic acid duplex with terminicorresponding to the ends of the specific primers employed.

Any source of nucleic acid, in purified or non purified form; can beutilized as the starting nucleic acid or acids, provided it contains oris suspected of containing the specific nucleic acid sequence desired.Thus, the process may employ, for example, DNA or RNA, includingmessenger RNA, which DNA or RNA may be single stranded or doublestranded. In addition, a DNA-RNA hybrid which contains one strand ofeach may be utilized. A mixture of any of these nucleic acids may alsobe employed, or the nucleic acid produced from a previous amplificationreaction herein using the same or different primers may be so utilized.The specific nucleic acid sequence to be amplified may be only afraction of a larger molecule or can be present initially as a discretemolecule, so that the specific sequence constitutes the entire nucleicacid. It is not necessary that the sequence to be amplified be presentinitially in a pure form; it may be a minor fraction of a complexmixture, such as a portion of the β-globin gene contained in whole humanDNA or a portion of nucleic acid sequence due to a particularmicroorganism which organism might constitute only a very minor fractionof a particular biological sample. The starting nucleic acid may containmore than one desired specific nucleic acid sequence which may be thesame or different. Therefore, it is useful not only for producing largeamounts of one specific nucleic acid sequence, but also for amplifyingsimultaneously more than one different specific nucleic acid sequencelocated on the same or different nucleic acid molecules.

The nucleic acid or acids may be obtained from any source, for example,from plasmids such as pBR322, from cloned DNA or RNA, or from naturalDNA or RNA from any source, including bacteria, yeast, viruses, andhigher organisms such as plants or animals. DNA or RNA may be extractedfrom blood, tissue material such as chorionic villi or amniotic cells.

It will be understood that the word primer as used hereinafter-may referto more than one primer, particularly in the case where there is someambiguity in the information regarding the terminal sequence(s) of thefragment to be amplified. For instance, in the case where a nucleic acidsequence is inferred from protein sequence information a collection ofprimers containing sequences representing all possible codon variationsbased on degeneracy of the genetic code will be used for each strand.One primer from this collection will be 100% homologous with the end ofthe desired sequence to be amplified.

An appropriate agent may be added for inducing or catalyzing the primerextension reaction and the reaction is allowed to occur under conditionsknown in the art. The inducing agent may be any compound or system whichwill function to accomplish the synthesis of primer extension products,including enzymes. Suitable enzymes for this purpose may include, forexample, E. coli DNA polymerase I, Klenow fragment of E. coli DNApolymerase I, T4 DNA polymerase, other available DNA polymerases,reverse transcriptase, and other enzymes, including heat-stable enzymes,which will facilitate combination of the nucleotides in the propermanner to form the primer extension products which are complementary toeach nucleic acid strand. Generally, the synthesis can be initiated atthe 3′end of each primer and proceed in the 5′ direction along thetemplate strand, until synthesis terminates, producing molecules ofdifferent lengths. There may be inducing agents, however, which initiatesynthesis at the 5′ end and proceed in the other direction, using thesame process as described above.

The newly synthesized strand and its complementary nucleic acid strandform a double-stranded molecule which can be used in the succeedingsteps of the process. In the next step, the strands of thedouble-stranded molecule may be separated to provide single-strandedmolecules. New nucleic acid may be synthesized on the single-strandedmolecules. Additional inducing agent, nucleotides and primers may beadded if necessary for the reaction to proceed under the conditionsprescribed above. Again, the synthesis would be initiated at one end ofthe oligonucleotide primers and would proceed along the single strandsof the template to produce additional nucleic acid. After this step,half of the extension product would consist of the specific nucleic acidsequence bounded by the two primers. The steps of strand separation andextension product synthesis can be repeated as often as needed toproduce the desired quantity of the specific nucleic acid sequence. Theamount of the specific nucleic acid sequence produced would accumulatein an exponential fashion. After the appropriate length of time haspassed to produce the desired amount of the specific nucleic acidsequence, the reaction may be halted by inactivating the enzymes in anyknown manner or separating the components of the reaction.

Amplification is useful when the amount of nucleic acid available foranalysis is very small, as, for example, in the prenatal diagnosis ofsickle cell anemia using DNA obtained from fetal cells. Amplification isparticularly useful if such an analysis is to be done on a small sampleusing non-radioactive detection techniques which may be inherentlyinsensitive, or where radioactive techniques are being employed butwhere rapid detection is desirable.

Any known techniques for nucleic acid (e.g., DNA and RNA) amplificationcan be used with the assays described herein. Preferred amplificationtechniques are the polymerase chain reaction (PCR) methodologies whichcomprise solution PCR and in situ PCR.

The invention is not limited to the use of straightforward PCR. A systemof nested primers may be used for example. Other suitable amplificationmethods known in the field can also be applied such as, but not limitedto, ligase chain reaction (LCR), strand displacement amplification(SDA), self-sustained sequence replication (3SR), array based test, andTAQMAN.

As used herein “amplification” may refer to any in vitro method forincreasing the number of copies of a nucleic acid sequence with the useof a DNA polymerase. Nucleic acid amplification results in theincorporation of nucleotides into a DNA molecule or primer therebyforming a new DNA molecule complementary to a DNA template. The newlyformed DNA molecule and its template can be used as templates tosynthesize additional DNA molecules. As used herein, one amplificationreaction may consist of many rounds of DNA replication. DNAamplification reactions include, for example, polymerase chain reactions(PCR). One PCR reaction may consist of 5-100 “cycles” of denaturation,annealing, and synthesis of a DNA molecule.

Fluorescence Microscopy

Some embodiments of the invention include fluorescence microscopy for adetection of a biological substance in a nasal specimen. Fluorescencemicroscopy enables the molecular composition of the structures beingobserved to be identified through the use of fluorescently-labeledprobes of high chemical specificity such as antibodies. It can be doneby directly conjugating a fluorophore to a protein and introducing thisback into a cell. Fluorescent analogue may behave like the nativeprotein and can therefore serve to reveal the distribution and behaviorof this protein in the cell. Along with NMR, infrared spectroscopy,circular dichroism and other techniques, protein intrinsic fluorescencedecay and its associated observation of fluorescence anisotropy,collisional quenching and resonance energy transfer are techniques forprotein detection.

The naturally fluorescent proteins can be used as fluorescent probes.The jellyfish aequorea victoria produces a naturally fluorescent proteinknown as green fluorescent protein (GFP). The fusion of thesefluorescent probes to a target protein enables visualization byfluorescence microscopy and quantification by flow cytometry. Withoutlimiting the scope of the present invention, some of the probes are asfollowing:

Labels: Sensitivity and safety (compared to radioactive methods) offluorescence has led to an increasing use for specific labeling ofnucleic acids, proteins and other biomolecules. Besides fluorescein,other fluorescent labels cover the whole range from 400 to 820 nm. Byway of example only, some of the labels are, fluorescein and itsderivatives, carboxyfluoresceins, rhodamines and their derivatives, attolabels, fluorescent red and fluorescent orange: Cy3/Cy5 alternatives,lanthanide complexes with long lifetimes, long wavelength labels—up to800 nm, DY cyanine labels, and phycobili proteins.

Conjugates: Antibody conjugates can be generated with specificity forvirtually any epitope and are therefore, applicable to imaging a widerange of biomolecules. By way of example only, some of the conjugatesare, isothiocyanate conjugates, streptavidin conjugates, and biotinconjugates.

Enzyme Substrates: By way of example only, some of the enzyme substratesare fluorogenic and chromogenic substrates.

Micro- and Nanoparticles: By way of example only, some of thefluorochromes are: FITC (green fluorescence,excitation/emission.=506/529 run), rhodamine B (orange fluorescence,excitation/emission=560/584 nm), and nile blue A (red fluorescence,excitation/emission=636/686 nm). Fluorescent nanoparticles can be usedfor various types of immunoassays. Fluorescent nanoparticles are basedon different materials, such as, polyacrylonitrile, and polystyrene etc.

Molecular Rotors: Fluorescent molecular rotors are sensors ofmicroenvironmental restriction that become fluorescent when theirrotation is constrained. Few examples of molecular constraint includeincreased dye (aggregation), binding to antibodies, or being trapped inthe polymerization of actin.

IEF-Markers: IEF (isoelectric focusing) is an analytical tool for theseparation of ampholytes, mainly proteins. An advantage for IEF-Gelelectrophoresis with fluorescent IEF-marker is the possibility todirectly observe the formation of gradient. Fluorescent IEF-marker canalso be detected by UV-absorption at 280 nm (20° C).

Any or all of these fluorescent probes can be used for the detection ofbiological substances in the nasal mucus. A peptide library can besynthesized on solid supports and, by using coloring receptors,subsequent dyed solid supports can be selected one by one. If receptorscannot indicate any color, their binding antibodies can be dyed. Themethod can not only be used on protein receptors, but also on screeningbinding ligands of synthesized artificial receptors and screening newmetal binding ligands as well. Automated methods for HTS and FACS(fluorescence activated cell sorter) can also be used. A FACS machineoriginally runs cells through a capillary tube and separate cells bydetecting their fluorescent intensities.

Immunoassays

Some embodiments of the invention include immunoassay for a detection ofa biological substance in a nasal specimen. In immunoblotting like thewestern blot of electrophoretically separated proteins a single proteincan be identified by its antibody. Immunoassay can be competitivebinding immunoassay where analyte competes with a labeled antigen for alimited pool of antibody molecules (e.g. radioimmunoassay, EMIT).Immunoassay can be non-competitive where antibody is present in excessand is labeled. As analyte antigen complex is increased, the amount oflabeled antibody-antigen complex may also increase (e.g. ELISA).Antibodies can be polyclonal if produced by antigen injection into anexperimental animal, or monoclonal if produced by cell fusion and cellculture techniques. In immunoassay, the antibody may serve as a specificreagent for the analyte antigen.

Without limiting the scope and content of the present invention, some ofthe types of immunoassays are, by way of example only, RIAs(radioimmunoassay), enzyme immunoassays like ELISA (enzyme-linkedimmunosorbent assay), EMIT (enzyme multiplied immunoassay technique),microparticle enzyme immunoassay (MEIA), LIA (luminescent immunoassay),and FIA (fluorescent immunoassay). These techniques can be used todetect biological substances in the nasal specimen. Theantibodies—either used as primary or secondary ones—can be labeled withradioisotopes (e.g. 1251), fluorescent dyes (e.g. FITC) or enzymes (e.g.HRP or AP) which may catalyse fluorogenic or luminogenic reactions.

EMIT (Enzyme Multiplied Immunoassay Technique): EMIT is a competitivebinding immunoassay that avoids the usual separation step. A type ofimmunoassay in which the protein is labeled with an enzyme, and theenzyme-protein-antibody complex is enzymatically inactive, allowingquantitation of unlabelled protein.

ELISA (Enzyme Linked Immunosorbent Assay): Some embodiments of theinvention include ELISA to detect biological substances in the nasalspecimen. ELISA is based on selective antibodies attached to solidsupports combined with enzyme reactions to produce systems capable ofdetecting low levels of proteins. It is also known as enzyme immunoassayor EIA. The protein is detected by antibodies that have been madeagainst it, that is, for which it is the antigen. Monoclonal antibodiesare often used.

The test may require the antibodies to be fixed to a solid surface, suchas the inner surface of a test tube, and a preparation of the sameantibodies coupled to an enzyme. The enzyme may be one (e.g.,β-galactosidase) that produces a colored product from a colorlesssubstrate. The test, for example, may be performed by filling the tubewith the antigen solution (e.g., protein) to be assayed. Any antigenmolecules present may bind to the immobilized antibody molecules. Theantibody-enzyme conjugate may be added to the reaction mixture. Theantibody part of the conjugate binds to any antigen molecules that werebound previously, creating an antibody-antigen-antibody “sandwich”.After washing away any unbound conjugate, the substrate solution may beadded. After a set interval, the reaction is stopped (e.g., by adding 1N NaOH) and the concentration of colored product formed is measured in aspectrophotometer. The intensity of color is proportional to theconcentration of bound antigen.

ELISA can also be adapted to measure the concentration of antibodies, inwhich case, the wells are coated with the appropriate antigen. Thesolution (e.g., serum) containing antibody may be added. After it hashad time to bind to the immobilized antigen, an enzyme-conjugatedanti-immunoglobulin may be added, consisting of an antibody against theantibodies being tested for. After washing away unreacted reagent, thesubstrate may be added. The intensity of the color produced isproportional to the amount of enzyme-labeled antibodies bound (and thusto the concentration of the antibodies being assayed).

Radioimmunoassay: Some embodiments of the invention includeradioimmunoassays to detect biological substances in the nasal specimen.Radioactive isotopes can be used to study in vivo metabolism,distribution, and binding of small amount of compounds. Radioactiveisotopes of ¹H, ¹²C, ³¹P, ³²S, and ¹²⁷I in body are used such as ³H,¹⁴C, ³²P, ³⁵S, and ¹²⁵I.

In receptor fixation method in 96 well plates, receptors may be fixed ineach well by using antibody or chemical methods and radioactive labeledligands may be added to each well to induce binding. Unbound ligands maybe washed out and then the standard can be determined by quantitativeanalysis of radioactivity of bound ligands or that of washed-outligands. Then, addition of screening target compounds may inducecompetitive binding reaction with receptors. If the compounds showhigher affinity to receptors than standard radioactive ligands, most ofradioactive ligands would not bind to receptors and may be left insolution. Therefore, by analyzing quantity of bound radioactive ligands(or washed-out ligands), testing compounds' affinity to receptors can beindicated.

The filter membrane method may be needed when receptors cannot be fixedto 96 well plates or when ligand binding needs to be done in solutionphase. In other words, after ligand-receptor binding reaction insolution, if the reaction solution is filtered through nitrocellulosefilter paper, small molecules including ligands may go through it andonly protein receptors may be left on the paper. Only ligands thatstrongly bound to receptors may stay on the filter paper and therelative affinity of added compounds can be identified by quantitativeanalysis of the standard radioactive ligands.

Fluorescence Immunoassays: Some embodiments of the invention includefluorescence immunoassays for a detection of a biological substance in anasal specimen. Fluorescence based immunological methods are based uponthe competitive binding of labeled ligands versus unlabeled ones onhighly specific receptor sites.

The fluorescence technique can be used for immunoassays based on changesin fluorescence lifetime with changing analyte concentration. Thistechnique may work with short lifetime dyes like fluoresceinisothiocyanate (FITC) (the donor) whose fluorescence may be quenched byenergy transfer to eosin (the acceptor). A number of photoluminescentcompounds may be used, such as cyanines, oxazines, thiazines,porphyrins, phthalocyanines, fluorescent infrared-emitting polynucleararomatic hydrocarbons, phycobiliproteins, squaraines and organo-metalliccomplexes, hydrocarbons and azo dyes.

Fluorescence based immunological methods can be, for example,heterogenous or homogenous. Heterogenous immunoassays comprise physicalseparation of bound from free labeled analyte. The analyte or antibodymay be attached to a solid surface. The technique can be competitive(for a higher selectivity) or noncompetitive (for a higher sensitivity).Detection can be direct (only one type of antibody used) or indirect (asecond type of antibody is used). Homogenous immunoassays comprise nophysical separation. Double-antibody fluorophore-labeled antigenparticipates in an equilibrium reaction with antibodies directed againstboth the antigen and the fluorophore. Labeled and unlabeled antigen maycompete for a limited number of anti-antigen antibodies.

Some of the fluorescence immunoassay methods include simple fluorescencelabeling method, fluorescence resonance energy transfer (FRET), timeresolved fluorescence (TRF), and scanning probe microscopy (SPM). Thesimple fluorescence labeling method method can be used forreceptor-ligand binding, enzymatic activity by using pertinentfluorescence, and as a fluorescent indicator of various in vivophysiological changes such as pH, ion concentration, and electricpressure. TRF is a method that selectively measures fluorescence of thelanthanide series after the emission of other fluorescent molecules isfinished. TRF can be used with FRET and the lanthanide series can becomedonors or acceptors. In scanning probe microscopy, in the capture phase,for example, at least one monoclonal antibody is adhered to a solidphase and a scanning probe microscope is utilized to detectantigen/antibody complexes which may be present on the surface of thesolid phase. The use of scanning tunneling microscopy eliminates theneed for labels which normally is utilized in many inmunoassay systemsto detect antigen/antibody complexes.

Nuclear Magnetic Resonanace (NMR)

Some embodiments of the invention include NMR for detection of abiological substance in a nasal specimen. NMR spectroscopy is capable ofdetermining the structures of biological macromolecules like proteinsand nucleic acids at atomic resolution. In addition, it is possible tostudy time dependent phenomena with NMR, such as intramolecular dynamicsin macromolecules, reaction kinetics, molecular recognition or proteinfolding. Heteronuclei like ¹⁵N, ¹³C and ²H, can be incorporated inproteins by uniform or selective isotopic labeling. Additionally, somenew information about structure and dynamics of macromolecules can bedetermined with these methods.

X-ray Crystallography

Some embodiments of the invention include X-ray crystallography fordetection of a biological substance in a nasal specimen. X-raycrystallography is a technique in which the pattern produced by thediffraction of X-rays through the closely spaced lattice of atoms in acrystal is recorded and then analyzed to reveal the nature of thatlattice. This generally leads to an understanding of the material andmolecular structure of a substance. The spacings in the crystal latticecan be determined using Bragg's law. X-ray diffraction is commonlycarried out using single crystals of a material, but if these are notavailable, microcrystalline powdered samples may also be used which mayrequire different equipment.

Fluorescence Spectroscopy

Some embodiments of the invention include fluorescence spectroscopy fordetection of a biological substance in a nasal specimen. By way ofexample only, conventional fluorometry is measurement of emission lightintensities at defined wavelengths for a certain emission maxima of afluorophore. Total fluorometry is a collection of data for a continuumof absorption as well as emission wavelengths. Fluorescence polarizationis when polarized light is used for excitation and binding offluorochrome-labeled antigens to specific antibodies. Line narrowingspectroscopy is low-temperature solid-state spectroscopy that derivesits selectivity from the narrow-line emission spectra.

Time-dependent fluorescence spectroscopy comprises time-resolvedmeasurements containing more information than steady-state measurements,since the steady-state values represent the time average oftime-resolved determinations. It is a single photon timing techniquewhere the time between an excitation light pulse and the first photonemitted by the sample is measured.

Matrix Assisted Laser Desorption Ionization Time-of-Flight MassSpectrometry (MALDI TOF-MS)

Some embodiments of the invention include MALDI TOF-MS for detection ofa biological substance in a nasal specimen. MALDI TOF-MS providesaccurate mass determinations and primary sequence information. Improvedmass resolution in MALDI TOF-MS can be obtained by the utilization of asingle-stage or a dual-stage reflectron (RETOF-MS). In the reflectronmass spectrum, the isotopic multiplet is well resolved producing a fullwidth half maximum (FWHM) mass resolution of about 3400. Massresolutions up to 6000 (FWHM) can be obtained for peptides up to about3000 Da with RETOF-MS. Enhancing the mass resolution can also increasethe mass accuracy when determining the ion's mass.

Both linear and reflectron MALDI-TOF-MS can be utilized for molecularweight determinations of molecular ions and enzymatic digests leading tostructural information of proteins. These digests are typically massanalyzed with or without purification prior to molecular weightdeterminations. Varieties of methodologies have been developed to obtainprimary sequence information for proteins and peptides utilizing MALDITOF-MS. Two different approaches can be taken. The first method is knownas protein ladder sequencing and can be employed to produce structurallyinformative fragments of the analyte prior to insertion into the TOFmass spectrometer and subsequent analysis. The second approach utilizesthe phenomenon of metastable ion decay that occurs inside the TOF massspectrometer to produce sequence information.

The ladder sequencing with TOF-MS consists of either a time-dependent orconcentration-dependent chemical degradation from either the N— orC-terminus of the protein/peptide into fragments, each of which differsby one amino acid residue. The mixture is mass analyzed in a singleMALDI TOF-MS experiment with mass differences between adjacent massspectral peaks corresponding to a specific amino acid residue. The orderof occurrence in the mass spectrum defines the sequence of amino acidsin the original protein/peptide.

Post-source decay with RETOF-MS MALDI is an ionization technique thatproduces intact protonated pseudomolecular ion species. A significantdegree of metastable ion decay occurs after ion acceleration and priorto detection. The ion fragments produced from the metastable ion decayof peptides and proteins typically include both neutral molecule losses(such as water, ammonia and portions of the amino acid side chains) andrandom cleavage at peptide bonds. In-source decay with linear TOF-MS isan alternative approach to RETOF-MS for studying metastable ion decay ofMALDI generated ions. Primary structural information for peptides andproteins can be obtained by this method. Coherent mass spectral peakscan be produced from these metastable decayed ions giving rise tosignificant structural information for peptides and proteins.

Surface-Enhanced Laser Desorption Ionization—Time Of Flight (SELDI-TOF)

Some embodiments of the invention include SELDI TOF-MS for detection ofa biological substance in a nasal specimen. This technique utilizesstainless steel or aluminum-based supports, or chips, engineered withchemical (hydrophilic, hydrophobic, pre-activated, normal-phase,immobilized metal affinity, and cationic or anionic) or biological(antibody, antigen binding fragments (e.g. scFv), DNA, enzyme, orreceptor) bait surfaces of 1-2mm in diameter. These varied chemical andbiochemical surfaces allow differential capture of proteins based on theintrinsic properties of the proteins themselves. Solubilized tissue orbody fluids in volumes as small as 0.1 μl can be directly applied tothese surfaces, where proteins with affinities to the bait surface maybind. Following a series of washes to remove non-specifically or weaklybound proteins, the bound proteins are laser desorbed and ionized for MSanalysis. Masses of proteins ranging from small peptides of less than1000 Da up to proteins of greater than 300 kDa can be calculated basedon time-of-flight. As mixtures of proteins may be analyzed withindifferent samples, a unique sample fingerprint or signature may resultfor each sample tested. Consequently, patterns of masses rather thanactual protein identifications can be produced by SELDI analysis. Thesemass spectral patterns can be used to differentiate patient samples fromone another, such as diseased from normal.

UV-vis

Some embodiments of the invention include optical absorptionspectroscopy (UV/VIS) for detection of a biological substance in a nasalspecimen. UV/VIS provides light absorption data which helps in thedetermination of concentration of macromolecules such as, proteins, DNA,nucleotides etc. Organic dyes can be used to enhance the absorption andto shift the absorption into the visible range (e.g. coomassie bluereagents). Resonance raman spectroscopy (RRS) can be used to studymolecular structure and dynamics. RRS helps in investigating specificparts of macromolecules by using different excitation wavelengths.

Liquid Chromatography (LC)

Some embodiments of the invention include LC for a detection ofbiological substance in a nasal specimen. Examples of LC are but notlimited to, affinity chromatography, gel filtration chromatography,anion exchange chromatography, cation exchange chromatography, diodearray-LC and high performance liquid chromatography (HPLC).

Gel filtration chromatography separates proteins, peptides, andoligonucleotides on the basis of size.′ Molecules may move through a bedof porous beads, diffusing into the beads to greater or lesser degrees.Smaller molecules may diffuse further into the pores of the beads andtherefore move through the bed more slowly, while larger molecules mayenter less or not at all and thus move through the bed more quickly.Both molecular weight and three dimensional shapes contribute to thedegree of retention. Gel Filtration Chromatography may be used foranalysis of molecular size, for separations of components in a mixture,or for salt removal or buffer exchange from a preparation ofmacromolecules.

Affinity chromatography is the process of bioselective adsorption andsubsequent recovery of a compound from an immobilized ligand. Thisprocess allows for the specific and efficient purification of manydiverse proteins and other compounds. Ion exchange chromatographyseparates molecules based on differences between the overall charges ofthe proteins. It can be used for the purification of protein,oligonucleotides, peptides, or other charged molecules.

HPLC can be used in the separation, purification and detection ofbiological substances in the nasal mucus. Crude tissue extracts may beloaded directly onto the HPLC system and mobilized by gradient elution.Rechromatography under the identical conditions is an option if furtherpurification is warranted or necessary. Reversed phase chromatography(RPC) can be utilized in the process of protein structure determination.HPLC may be coupled with MS. The HPLC method described in Henkin et al.,New Frontiers in Immunobiology, 2000, pp. 127-152, is incorporatedherein in its entirety.

The size-exclusion chromatography (SEC) and ion-exchange chromatography(IEC) can be used for separation and purification of biologically activeproteins, such as enzymes, hormones, and antibodies. In liquid affinitychromatography (LAC), interaction may be based on binding of the proteindue to mimicry of substrate, receptor, etc. The protein may be eluted byintroducing a competitive binding agent or altering the proteinconfiguration which may facilitate dissociation. A procedure that can beused in the separation of membrane proteins is the use of nonionicdetergents, such as Triton X-1 00, or protein solubilization by organicsolvents with IEC.

Diode array detector-liquid chromatography (DAD-LC) provides complete,multiple spectra for each HPLC peak, which, by comparison, can provideindication of peak purity. These data can also assign presence of tyr,trp, phe, and possibly others (his, met, cys) and can quantitate theseamino acids by 2nd derivative or multi-component analysis. By apost-column derivatization, DAD-LC can also identify and quantitate cys,his and arg in individual peptides. Thus, it is possible to analyze for6 of the 20 amino acids of each separated peptide in a single LC run,and information can be obtained about presence or absence of these aminoacids in a given peptide in a single step. This is assisted by knowingthe number of residues in each peptide.

Electrophoresis

Some embodiments of the invention include electrophoresis for detectionof a biological substance in a nasal specimen. Electrophoresis can begel electrophoresis or capillary electrophoresis.

Gel Electrophoresis: Gel electrophoresis is a technique that can be usedfor the separation of proteins. During electrophoresis, macromoleculesare forced to move through pores when an electrical current is applied.Their rate of migration through the electric field depends on strengthof the field, size and shape of the molecules, relative hydrophobicityof the samples, and on an ionic strength and temperature of a buffer inwhich the molecules are moving. After staining, the separatedmacromolecules in each lane can be seen in a series of bands spread fromone end of the gel to the other. Using this technology it is possible toseparate and identify protein molecules that differ by as little as asingle amino acid. Also, gel electrophoresis allows determination ofcrucial properties of a protein such as its isoelectric point andapproximate molecular weight. Electrofocusing or isoelectric focusing isa technique for separating different molecules by their electric chargedifferences (if they have any charge). It is a type of zoneelectrophoresis that takes advantage of the fact that a molecule'scharge changes as the pH of its surroundings changes.

Capillary Electrophoresis: Capillary electrophoresis is a collection ofa range of separation techniques which may involve the application ofhigh voltages across buffer filled capillaries to achieve separations.The variations include separation based on size and charge differencesbetween analytes (termed capillary zone electrophoresis (CZE) or freesolution CE (FSCE)), separation of neutral compounds using surfactantmicelles (micellar electrokinetic capillary chromatography (MECC) orsometimes referred to as MEKC) sieving of solutes through a gel network(capillary gel electrophoresis, GCE), separation of cations (or anions)based on electrophoretic mobility (capillary isotachophoresis, CITP),and separation of zwitterionic solutes within a pH gradient (capillaryisoelectric focusing, CIEF). Capillary electrochromatography (CEC) canbe an associated electrokinetic separation technique which involvesapplying voltages across capillaries filled with silica gel stationaryphases. Separation selectivity in CEC can be a combination of bothelectrophoretic and chromatographic processes. Many of the CE separationtechniques rely on the presence of an electrically induced flow ofsolution (electroosmotic flow, EOF) within the capillary to pump solutestowards the detector.

Arrays

Some embodiments of the invention include arrays for detection of abiological substance in a nasal specimen. Arrays involve performingparallel analysis of multiple samples against known protein targets. Thedevelopment of various microarray platforms can enable and acceleratethe determination of protein abundance, localization, and interactionsin a cell or tissue. Microarrays provide a platform that allowsidentification of protein interaction or function against acharacterized set of proteins, antibodies, or peptides. Protein-basedchips array proteins on a small surface and can directly measure thelevels of proteins in tissues using fluorescence-based imaging. Proteinscan be arrayed on either flat solid phases or in capillary systems(microfluidic arrays), and several different proteins can be applied tothese arrays. In addition to the use of antibodies as array probes,single-stranded oligonucleotides, whose specificity is optimized by invitro elution (aptamers), offer a viable alternative. Nonspecificprotein stains can be then used to detect bound proteins.

Arrays include, but are not limited to, bead arrays, bead based arrays,bioarrays, bioelectronic arrays, cDNA arrays, cell arrays, DNA arrays,gene arrays, gene expression arrays, frozen cell arrays, genome arrays,high density oligonucleotide arrays, hybridization arrays,microcantilever arrays, microelectronic arrays, multiplex DNAhybridization arrays, nanoarrays, oligonucleotide arrays,oligosaccharide arrays, planar arrays, protein arrays, solution arrays,spotted arrays, tissue arrays, exon arrays, filter arrays, macroarrays,small molecule microarrays, suspension arrays, theme arrays, tilingarrays, and transcript arrays.

Sensors

Some embodiments of the invention include sensors for detection of abiological substance in a nasal specimen. Sensors can be used for bothin vivo and in vitro detection. Sensors can be chemical sensors, opticalsensors, and biosensors. Chemical sensors are miniaturized analyticaldevices which may deliver real-time and online information on thepresence of specific compounds or ions in complex samples. Opticalsensors are based on measurement of either intrinsic optical propertiesof analytes, or of optical properties of indicator dyes or labeledbiomolecules attached to solid supports. Biosensors can be affinitybiosensor based on capabilities of enzymes to convert substrates intoproducts or catalytic biosensors. Biosensors detect antibody and analytecomplexes using a variety of physical methods. Some biosensors measurethe change in surface charge that occurs when analyte is bound toantibodies or other binding agents, which in turn are bound to asurface. Other biosensors use binding agents attached to a surface andmeasure a change in a physical property of the support, other thansurface charge, upon binding of analyte. Some biosensor techniques use aspecific property of a labeled binding agent or antigen to produce ameasurable change.

Methods for Identifying Proteins from a Library Screen

Protein identification methods by way of example only includelow-throughput sequencing through Edman degradation, mass spectrometrytechniques, peptide mass fingerprinting, de novo sequencing, andantibody-based assays. The protein quantification assays includefluorescent dye gel staining, tagging or chemical modification methods(i.e. isotope-coded affinity tags (ICATS), combined fractional diagonalchromatography (COFRADIC)). The purified protein may also be used fordetermination of three-dimensional crystal structure, which can be usedfor modeling intermolecular interactions. Common methods for determiningthree-dimensional crystal structure include x-ray crystallography andNMR spectroscopy. Detailed below are a few of the methods foridentifying proteins in the present invention.

Protein sequencing: N-terminal sequencing aids in the identification ofunknown proteins, confirm recombinant protein identity and fidelity(reading frame, translation start point, etc.), aid the interpretationof NMR and crystallographic data, demonstrate degrees of identitybetween proteins, or provide data for the design of synthetic peptidesfor antibody generation, etc. N-terminal sequencing utilises the Edmandegradative chemistry, sequentially removing amino acid residues fromthe N-terminus of the protein and identifying them by reverse-phaseHPLC. Sensitivity can be at the level of 100s femtomoles and longsequence reads (20-40 residues) can often be obtained from a few 10 spicomoles of starting material. Pure proteins (>90%) can generate easilyinterpreted data, but insufficiently purified protein mixtures may alsoprovide useful data, subject to rigorous data interpretation.N-terminally modified (especially acetylated) proteins cannot besequenced directly, as the absence of a free primary amino-groupprevents the Edman chemistry. However, limited proteolysis of theblocked protein (e.g. using cyanogen bromide) may allow a mixture ofamino acids to be generated in each cycle of the instrument, which canbe subjected to database analysis in order to interpret meaningfulsequence information. C-terminal sequencing is a post-translationalmodification, affecting the structure and activity of a protein. Variousdisease situations can be associated with impaired protein processingand C-terminal sequencing provides an additional tool for theinvestigation of protein structure and processing mechanisms.

Proteome analyses: Proteomics can be identified primarily by computersearch algorithms that assign sequences to a set of empirically acquiredmass/intensity data which are generated from conducting electrosprayionization (ESI), matrix-assisted laser desorption/ionization(MALDI-TOF), or three-dimensional quadrupole ion traps on the protein ofinterest.

Diagnosis

The identification and analysis of biological substances as disclosedherein has numerous therapeutic and diagnostic applications. Clinicalapplications include, for example, detection of disease, distinguishingdisease states to inform prognosis, selection of therapy, and/orprediction of therapeutic response, disease staging, identification ofdisease processes, prediction of efficacy of therapy, monitoring ofpatients trajectories (e.g., prior to onset of disease), prediction ofadverse response, monitoring of therapy associated with efficacy andtoxicity, and detection of recurrence.

Measuring a concentration of the biological substance can aid in thediagnosis of a course of a disease. For example, the diabetic state of apatient who was previously diagnosed with diabetes can be determined bymonitoring the nasal secretions of the patient for insulin. A biologicalsubstance, for example, growth factor may be one that is specific forthe patient's specific disease. Alternatively, a panel of two or morespecific or non-specific growth factors may be monitored. Theconcentrations of either an individual factor or several factors, in thebiological sample of the patient may be affected by the disease.

The presence or increase or decrease of biological substances′concentration allows the physician or veterinarian to predict the courseof the disease or the efficacy of treatment regimes. If, for example, apatient who had a certain type of disease, which was treated,subsequently exhibits an increase in the concentration of biologicalsubstances that is associated with that disease, the physician orveterinarian can predict that the patient may have progression of thedisease in the future or predict a higher risk of fatality in thepatient. In addition, the amount of biological substances may bepredictive of the outcome of the patient, e.g., how well certainchemotherapeutic agents may act.

One aspect of the present invention is a method of diagnosing a diseaseby obtaining a specimen of nasal secretion, detecting a biologicalsubstance in the specimen, and diagnosing the disease wherein thediagnosis is based on the detection of the biological substance, andwherein the biological substance is not related to a respiratorydisease. In one embodiment leprosy is diagnosed by detection ofantibodies against leprosy causing pathogen for example, mycobacteriumleprae. In one embodiment hepatitis, such as hepatitis A, B, C, D, E,and G, is diagnosed by detection of antibodies against hepatitis causingvirus. In some embodiments, the biological substances include insulin orinsulin receptors for a diagnosis of diabetes. In some embodiments, thebiological substance is p53 for a diagnosis of cancer.

Some embodiments of the invention include diagnosing diabetes bydetecting insulin or insulin receptor in the nasal specimen. Table 6depicts detection and measurement of human insulin concentration innasal mucus as compared to insulin concentration in blood plasma andsaliva. Table 7 depicts the detection and measurement of human insulinreceptor concentration in nasal mucus as compared to the insulinreceptor concentration in plasma and saliva. The appearance of insulinor insulin receptors in nasal mucus refects either their synthesis innasal serous glands or response to a physiological and/or pathologicalphenomena. The presence of insulin or insulin receptors in nasal mucusoffers a non-invasive method for the diagnosis of diabetes and otherdisorders of carbohydrate metabolism.

Some embodiments of the invention include diagnosing cancer by detectingcaspase in the nasal specimen. Cysteine-dependent aspartate-specificproteases (caspases) are a family of proteases that cleave theirsubstrates at aspartic acid (D)-X bonds. 14 mammalian caspases have beenidentified. Caspase-2, -3, -6, -7, -8, -9 and -10 are major players inthe execution phase of apoptosis, whereas caspase-1, -4, -5, and -11 areinvolved in cytokine processing associated with inflammation. Caspase 3,also known as CPP32, cleaves and activates a variety of proteins such assterol regulatory element binding proteins (SREBPs). Caspase-3 alsocleaves poly (ADP-ribose) polymerase (PARP) at the onset of apoptosisand amyloid β precursory protein (APP) which is associated with neuronaldeath in Alzheimer's disease. Caspase 3 is activated by graszyne β,ADAF-1, caspase 9 and caspases 6, 8 and 10. This substance is one of theapoptotic substances found during the apoptotic process. Table 10illustrates a comparison between the detection of caspase 3 in nasalmucus as well as saliva. The presence of caspase in nasal mucus is about13% of that in saliva and reflects the magnitude of the apoptoticprocess. The presence of caspase in nasal mucus indicates the activityof cellular death in nasal mucus and shows that cancer can be diagnosedby detecting caspase in the nasal specimen.

Some embodiments of the invention include diagnosing cancer, taste lossor smell loss by detecting tumor necrosis factor a (TNFα) in the nasalspecimen. TNFα is a 17 KD cleavage product mediated by TNFα convertingenzyme which interacts with two distinct TNFα receptors (I, II) on thecell surface. TNFα is upregulated in many pathological processesinvolving inflammation and oncological processes such as rheumatoidarthritis, refractory bronchial asthma, liver disease, cancer and inpatients with taste and smell loss. It is also called cachectin and isproduced by many normal and tumor cells in response to a wide variety ofstimuli including viruses, bacteria, parasites, cytokines and mitogens.Both the transmembrane and the soluble secreted forms of TNFα arebiologically active. TNFα is an extremely pleotrophic cytokine due tothe ubiquity of its receptors, its ability to activate multiple signaltransduction pathways and its ability to induce or suppress theexpression a large number of genes.

Detecting the levels of TNFα in nasal mucus as disclosed herein makesthe diagnosis of a disease possible on a clinical basis since obtainingcellular diagnosis through tissue biopsy can not only be invasive butalso can be difficult and at times dangerous. Table 11 illustratesdetection and measurement of TNFα in nasal mucus and saliva in 75subjects. Results indicate that TNFα in nasal mucus is about 30 timeshigher than in saliva. These data suggest that various cancers can bediagnosed by measurements of TNFα in nasal mucus and their treatment canbe monitored by following-its concentration in nasal mucus. Since levelsof TNFα may also reflect the inflammatory aspects of disease processesinducing it, use of anti TNFα drugs through nasal administration reflecta method of treating these various disease processes. Concentrations ofTNFα in nasal mucus in patients with smell loss can be greater than forexample, 5000 times that found in normal subjects thereby reflecting itsfunction as a “death protein” indicator of excessive apoptosis as in itsrole in cancer.

Monitoring the levels of TNFα in nasal mucus may help in diagnosis ofarterial venous malfunction (AVM). AVM is normally diagnosed by MRI butdetection and measurement of TNFα in nasal mucus provides a non-invasivemethod of diagnosing AVM. Monitoring the level of TNFα can help indiagnosing the progression or stage of AVM or the susceptibility of thesubject towards AVM.

Some embodiments of the invention include diagnosing cancer, taste lossor smell loss by detecting tumor necrosis factor receptor I (TNFR I) inthe nasal specimen. TNF receptor I (TNFRI) is one of the two cellularreceptors upon which TNFα operates. It is one of the prototypic membersof the TNF receptor super family members designated TNFRSF I α. Indisease processes associated with increased TNFα activity TNFR I may beupregulated. Its presence in nasal mucus can reflect the activity ofmany inflammatory, oncological and other pathological processes,including taste and smell dysfunction. Table 12 illustrates detectionand measurement of TNFR I in 47 subjects. Results indicate that TNFR Iin nasal mucus is about 16 times its concentration in saliva and itsconcentration is significantly increased over that found in plasma, redblood cells, or urine. Thus -the detection of TNFR I in the nasalspecimen can be used to establish clinical diagnoses of excessiveapoptosis and can be used as a treatment modality in inhibitingpathological apoptosis.

TNFR II is the other of the two cellular receptors upon which TNFαoperates. TNFR II is one of the high-affinity receptors for TNFα and isone of the prototypic members of the TNF super family members designatedTNFSF I β. TNFR II may be upregulated in many inflammatory andoncological disease processes. It may also be solubilized and haveproperties similar to TNFR I. Table 13 illustrates detection andmeasurement of TNFR II in 47 subjects. Results indicate that TNFR II innasal mucus is about 24 times its concentration in saliva and itsconcentration in nasal mucus is significantly higher than found inplasma, rbcs, or urine. The results reflect that detection of TNFR II innasal specimen can provide a non invasive method of diagnosing variouspathological processes related to TNFR II.

TNF related apoptosis-inducing ligand (TRAIL) is also known as apo-2ligand and TNFSF-10.

BDNF is requiredfor differentiation and survival of specific subpopulations in bothcentral and peripheral nervous systems. High levels of BDNF expressionhave been found in hippocampus, cerebellumn, fetal eye and placenta.Table 22 in the examples illustrates detection and measurement of BDNFin plasma, urine, saliva and nasal mucus in 20 subjects. BDNF was foundin plasma and nasal mucus but not in urine or saliva. Levels of BDNF inplasma were higher than in nasal mucus. The results indicate that nasalmucus is a repository of the family of nerve growth factors and theconcentration of BDNF as shown in Table 22, may help understand bothphysiology and pathology of neurotrophic factors related to growth andhomeostasis of cells in the nasal cavity as well as reporting on thepresence of these factors in the systemic circulation. Presence of BDNFin nasal mucus illustrates a non-invasive method of detection of BDNF innasal mucus and its use in diagnosing various diseases. The diagnosiscan further lead to treatment of diseases by modulating theconcentration of BDNF with drugs. In some embodiments, the treatment isby nasal administration.

Some embodiments of the invention include diagnosing disease bydetecting ciliary neurotrophic factor in the nasal specimen. Ciliaryneurotrophic factor (CNTF) is structurally related to IL-6, IL-11, L1F,CLC and OSM. CNTF is a trophic factor for embryonic chick ciliaryparasympathetic neurons in culture. CNTF is also a survival factor foradditional numerous cell types including dorsal root ganglion sensoryneurons, sympathetic ganglion neurons, embryonic motor neurons, majorpelvic ganglion neurons and hippocampal neurons.

It is identical to scatter factor,a fibroblast-derived soluble factor that promotes the dissociation ofepithelial and vascular endothelial cell colonies in monolayes culturesby stimulating cell migration. Table 25 in the examples illustratesdetection and measurement of HGF in plasma, urine, saliva and nasalmucus in 17 subjects. Concentrations of HGF in nasal mucus were found tobe higher than that found in either plasma or urine. These resultssuggest that HGF may be synthesized in the serous glands of the nose fora specific mechanism involved with nasal homeostasis as well as amechanism involved with systemic cell migration. The results provide anon-invasive method for the detection of HGF in nasal mucus. Thedetection of HGF in nasal mucus provides a non invasive method ofdiagnosing various diseases related to human physiology and pathology.The diagnosis further leads to a treatment of diseases by modulating theconcentrations of HGF by use of drugs.

Some embodiments of the invention include diagnosing disease bydetecting platelet derived growth factor in the nasal specimen. Plateletderived growth factor (PDGF) family is a group of disulfide-linkeddimeric proteins which act mainly on connective tissue. This family mayconsist of four homodimeric proteins, PDGF-AA, PDGF-BB, PDGF-CC andPDGF-DD and one heterodimeric protein, PDGF-AB. The technique of ELISAmeasurement used is associated with the ability of PDGF to stimulateincorporation of 3H-thymidine in quiescent NRGR-3 T 3 fibroblastis.Table 26 in the examples illustrates detection and measurement of PDGFin human plasma, urine, saliva and nasal mucus in 18 subjects.Concentrations of PDGF expressed per mg protein were found to be higherin saliva and nasal mucus than in plasma. These results suggest thatPDGF may be synthesized in the serous glands of the nose for a specificmechanism involved with nasal homeostasis. The results provide anon-invasive method for the detection of PDGF in nasal mucus. Thedetection of PDGF in nasal mucus provides a non invasive method ofdiagnosing various diseases related to human physiology and pathology.The diagnosis can provide treatment of diseases by modulating theconcentrations of PDGF by use of drugs.

Some embodiments of the invention include diagnosing taste loss or smellloss by detecting carbonic anhydrase in the nasal specimen. Carbonicanhydrase is a zinc-containing enzyme and at least twenty carbonicanhydrase variants, called “isozymes” have been identified. CarbonicAnhydrase VI (CA VI) is a 36 KD zinc metalloglycoprotein. Its synthesisin nasal mucus may take place in nasal serous glands (in the oralparotid glands). It can act as a taste bud growth factor in the oralcavity and as an olfactory receptor growth factor in the nasal cavity.It can also act on taste bud and olfactory receptor stem cells to inducegrowth and development of the entire panoply of cell types for the tastebuds and olfactory epithelium. Its decreased synthesis may induce bothloss of taste and smell. Its resumed synthesis may return cell growth tonormal. Treatment which increases synthesis of CA VI may involve severalcomplex processes including increasing zinc-cofactor concentration.Administration of zinc ion to some patients who are either zincdeficient or who may have metabolic processes which inhibit zincincorporation into the protein, may have their taste and smell functionimproved through this treatment. Since the carbohydrates in this proteinare part of its function, any process that repairs glycoproteinincorporation into this protein may also therapeutically be effective inrestoring taste and smell function.

Table 27 in the examples illustrates decrease in CA VI in patients withsmell and taste loss. Table 28 in the examples illustrates loss of smellfunction by disease etiology with respect to measurements of CA VIconcentration in nasal mucus. Results indicate that patients with postinfluenza hyposmia hypogeusia (PIHH), allergic rhinitis and postanesthesia have significantly decreased CA VI concentrations in nasalmucus. These results provide a method for the detection and measurementof CA VI in nasal mucus as an index of smell and taste loss and itscontinual measurement during treatment of these disorders in order tomonitor efficacy of therapy. The detection of CA VI in nasal mucusprovides a non invasive method of diagnosing various diseases related tohuman physiology and pathology. The diagnosis can further lead totreatment of diseases by modulating the concentrations of CA VI by useof drugs

Some embodiments of the invention include diagnosing a disease bydetecting cAMP and cGMP in the nasal specimen. Table 29 in the examplesillustrates detection and measurement of cAMP and cGMP in saliva and innasal mucus in normal subjects. Table 30 in the examples illustratescomparison of the measurement of cAMP and cGMP in normal subjects withthe patients with taste and smell loss. Results indicated that patientswith smell loss had decreased levels of cAMP in their nasal mucus. Theseresults indicate that cAMP in nasal mucus can be an index of smell lossand that its secretion may be inhibited in smell loss. The resultsprovide a non-invasive method for the detection of cAMP and cGMP innasal mucus.

Table 31 in the examples illustrates detection and measurement of cAMPand cGMP secretion in nasal mucus in patients with graded severity ofsmell loss (anosmia<Type I hyposmia<Type II hyposmia from most severe toleast severe). Data indicates that as degree of smell loss increased,levels of cAMP in nasal mucus decreased. These data confirm therelationship between cAMP secretion in nasal mucus and degree of smellloss. Results also indicate that there was less significant differencebetween cGMP in nasal mucus in normal subjects or in patients withhyposmia. However, the concentration of cGMP in saliva is essentiallysimilar to that of cAMP, phenomena different from that observed in othertissues.

The ability to smell and, in part, the ability to taste or to obtainflavor from food is regulated by the olfactory nerve system. Theolfactory nerve system is complex and interconnected with severalsystems in the brain. Olfactory receptors located in the nose arespecialized bipolar neurons with cilia protruding into the mucouscovering the epithelium. The axons of the bipolar neurons are packedinto bundles that form connections in the olfactory bulb in the brain.The olfactory bulbs contain a rich supply of neurotransmitters andneuromodulators. Chemosensory dysfunctions are usually described by thefollowing terms: ageusia (absence of taste), hypogeusia, (diminishedsensitivity of taste), dysgeusia (distortion of normal taste), anosmia(absence of smell), hyposmia (diminished sense of smell), and dysosmia(distortion of normal smell).

Treatment with drugs which increase cAMP secretion (e.g., thephosphodiesterase theophylline or cilostazol) increases nasal mucus cAMPconcentration and are associated with increases in smell function. Thus,cAMP measurements are critical to monitor both loss of smell functionand changes in smell function following treatment. The detection of cAMPand cGMP in nasal mucus provides a non invasive method of diagnosingvarious diseases related to human physiology and pathology. The methodsof the present invention include treatment of diseases by modulating theconcentrations of cAMP and cGMP by use of drugs or agents. The method oftreatment is preferably by nasal administration.

Some embodiments of the invention include diagnosing a disease bydetecting nitric oxide in the nasal specimen. Nitric Oxide (NO) is apletrophic-signaling molecule implicated in diverse biological processesincluding inhibition of platelet aggregation, regulation ofneurotransmission, vasodilation, immune responses and inflammation. NOis synthesized from arginine and O₂ by three nitric oxide synthase(NOS), enzymes endothelial NOS (eNOS), neuronal NOS (nNOS), andinducible NOS (iNOS). Each enzyme isoform is expressed in a variety oftissues and cell types. While eNOS and nNOS generally exhibitconstitutive expression and are involved in physiological signaling andcellular maintenance functions, iNOS expression may be induced byinflammatory stimuli and may be associated with both normal andpathological immune responses. Table 32 in the examples illustratesdetection and measurement of NO in human saliva and nasal mucus. NO wasfound to be present is in both saliva and nasal mucus and its meanconcentration in saliva were 21% lower in patients than in normalsubjects whereas in nasal mucus mean levels were 25% lower in patients.Treatment which increases cAMP in nasal mucus and improves smellfunction may be mirrored by increases in nasal mucus NO.

Some embodiments of the invention include diagnosing a disease bydetecting insulin-like growth factor I in the nasal specimen.Insulin-like growth factor I (IGF 1), also known as somatomedin Cbelongs to the family of insulin-like growth factors that arestructurally homologous to proinsulin. IGF 1 is a potent mitogenicfactor that mediates growth-promoting activities of growth hormonepostnatally. IGF 1 also promotes growth during embryonic growth anddifferentiation. Table 34 in the examples illustrates detection andmeasurement of IGF 1 in human saliva and nasal mucus in 26 subjects.Results show that IGF 1 concentration in nasal mucus was significantlygreater than in saliva. Results indicate that the measurement of nasalmucus IGF 1 can be used as an index of human physiology and pathology.The detection of IGF 1 in nasal mucus provides a non invasive method ofdiagnosing various diseases related to human physiology and pathology.The diagnosis can further help in treatment of diseases by modulatingthe concentrations of IGF 1 by use of drugs.

Some embodiments of the invention include diagnosing a disease bydetecting endoglin in the nasal specimen. Endoglin, also known as CD105, is a type 1 integral membrane glycoprotein and is an accessoryreceptor for TGF-β super family ligands. Endoglin is expressed onvascular endothelial cells, chrondrocytes and syncytiotrophoblasts ofterm placenta. It is also found on activated monocytes, mesenchymol stemcells and leukemic cells of lymphoid and myeloid lineages. Table 39illustrates detection and measurement of endoglin in the nasal mucus.Results indicate that the measurement of nasal mucus endoglin can beused as an index of human physiology and pathology. The detection ofendoglin in nasal mucus provides a non invasive method of diagnosingvarious diseases related to human physiology and pathology.

Some embodiments of the invention include diagnosing a disease bydetecting fibroblast growth factor (FGF) in the nasal specimen. FGFacidic is a member of the FGF family of mitogenic peptides. Unlike othermembers of the family, it lacks signal peptides. FGF is apparentlysecreted by mechanisms other than the classical protein secretionpathways. There are approximately 23 distinct members of this family.The nucleotide sequence of human FGF acidic is well known and it is a155 amino acid protein. FGF mediates cellular responses by binding toand activating a family of four receptor tyrosine kinases. FGF isinvolved in wound healing as it binds heparin. It promotes endothelialcell proliferation by physical organization of endothelial cells intotubes. It promotes angiogenesis and stimulates the proliferation offibroblasts that give rise to granulation tissue. It is a more potentangiogenic factor than either VFGF or PDGF. It acts on PC 12 cells;these cells also respond to NGF in a similar manner. Low levels of FGFhave been found in blood of patients with depression. Acidic FGF wasmeasured in blood plasma, urine, saliva and nasal mucus in 13 subjects.No FGF was found in any sample of plasma, urine or saliva. FGF wasmeasured in three samples of the nasal mucus or in 23 percent of thesubjects. Values ranged from 8-44 pg/mi with a mean±SEM of 24±13 pg/ml.These results suggest that FGF is present in nasal mucus and may be partof a feedback mechanism involving nasal cavity and brain since FGF issynthesized in the brain.

Detection of the concentration of the caspases in the nasal secretioncan provide diagnosing a disorder or selection of therapeutic strategiesinvolving, e.g., inappropriate apoptosis and/or excessive cellproliferation, such as an inflammatory disease, a neurodegenerativedisease, cancer, a cardiovascular disease and, any disorder or diseasecharacterized by a gradual and prolonged development of apoptosis.Apoptosis functions in maintaining normal tissue homeostasis in avariety of physiological processes including embryonic development,immune cell regulation, normal cellular turnover and programmed celldeath of cancer cells. Thus, the dysfunction or loss of regulatedapoptosis can lead to a variety of pathological disease states. Forexample, the loss of apoptosis can lead to the pathological accumulationof self-reactive lymphocytes such as occurs in many autoimmune diseases.Inappropriate loss of apoptosis can also lead to the accumulation ofvirally infected cells and of hyperproliferative cells such asneoplastic or tumor cells. Inappropriate activation of apoptosis cancontribute to a variety of diseases such as AIDS, neurodegenerativediseases and ischemic injury.

Dysregulation of apoptosis has been implicated in numerous diseases suchas neurodegenerative disorders including Alzheimer's disease,Parkinson's disease, Huntington's disease, and amyotrophic lateralsclerosis (ALS), cerebellar degeneration, stroke, traumatic braininjury, CNS ischemic reperfusion injury including neonatalhypoxic-ischemic brain injury or myocardial ischemic-reperfusion injury,injury caused by hypoxia, cardiovascular diseases (e.g., myocardialinfarction), especially those which are associated with apoptosis ofendothelial cells, degenerative liver disease, multiple sclerosis,rheumatoid arthritis, hematological disorders including lymphoma,leukemia, aplastic anemia, and myelodysplastic syndrome, osteoporosis,polycystic kidney disease, AIDS, myelodysplastic syndromes, aplasticanemia and baldness. Diseases of the eye include glaucoma, retinitispigmentosa and macular degeneration.

Inflammatory disease states include systemic inflammatory conditions andconditions associated locally with migration and attraction ofmonocytes, leukocytes and/or neutrophils. Inflammation may result frominfection with pathogenic organisms (including gram-positive bacteria,gram-negative bacteria, viruses, fungi, and parasites such as protozoaand helminths), transplant rejection (including rejection of solidorgans such as kidney, liver, heart, lung or cornea, as well asrejection of bone marrow transplants including graft-versus-host disease(GVHD)), or from localized chronic or acute autoimmune or allergicreactions. Autoinmmune diseases include acute glomerulonephritis;rheumatoid or reactive arthritis; chronic glomerulonephritis;inflammatory bowel diseases such as Crohn's disease, ulcerative colitisand necrotizing enterocolitis; granulocyte transfusion associatedsyndromes; inflammatory dermatoses such as contact dermatitis, atopicdermatitis, psoriasis; systemic lupus erythematosus (SLE), autoimmunethyroiditis, multiple sclerosis, and some forms of diabetes, or anyother autoimmune state where attack by the subject's own immune systemresults in pathologic tissue destruction. Allergic reactions includeallergic asthma, chronic bronchitis, acute and delayed hypersensitivity.Systemic inflammatory disease states include inflammation associatedwith trauma, burns, reperfusion following ischemic events (e.g.thrombotic events in heart, brain, intestines or peripheral vasculature,including myocardial infarction and stroke), sepsis, ARDS or multipleorgan dysfunction syndrome. Inflammatory cell recruitment also occurs inatherosclerotic plaques.

Examples of pathological conditions resulting from increased cellsurvival include cancers such as lymphomas, carcinomas andhormone-dependent tumors (e.g., breast, prostate or ovarian cancer).Abnormal cellular proliferation conditions or cancers that may betreated in either adults or children include solid phasetumors/malignancies, locally advanced tumors, human soft tissuesarcomas, metastatic cancer, including lymphatic metastases, blood cellmalignancies including multiple myeloma, acute and chronic leukemias,and lymphomas, head and neck cancers including mouth cancer, larynxcancer and thyroid cancer, lung cancers including small cell carcinomaand non-small cell cancers, breast cancers including small cellcarcinoma and ductal carcinoma, gastrointestinal cancers includingesophageal cancer, stomach cancer, colon cancer, colorectal cancer andpolyps associated with colorectal neoplasia, pancreatic cancers, livercancer, urologic cancers including bladder cancer and prostate cancer,malignancies of the female genital tract including ovarian carcinoma,uterine (including endometrial) cancers, and solid tumor in the ovarianfollicle, kidney cancers including renal cell carcinoma, brain cancersincluding intrinsic brain tumors, neuroblastoma, astrocytic braintumors, gliomas, metastatic tumor cell invasion in the central nervoussystem, bone cancers including osteomas, skin cancers includingmalignant melanoma, tumor progression of human skin keratinocytes,squamous cell carcinoma, basal cell carcinoma, hemangiopericytoma andKarposi's sarcoma.

Viral infections that may be detected include infections caused byherpesviruses (including CMV, HSV-1, HSV-2, VZV, EBV, HHV-6, HHV-7 andHHV-8), paramyxoviruses (including parainfluenza, mumps, measles, andrespiratory syncytial virus (RSV)), picornaviruses (includingenteroviruses and rhinoviruses), togaviruses, coronaviruses,arenaviruses, bunyaviruses, rhabdoviruses, orthomyxoviruses (includinginfluenza A, B and C viruses), reoviruses (including reoviruses,rotaviruses and orbiviruses), parvoviruses, adenoviruses, hepatitisviruses (including A, B, C, D and E) and retroviruses (including HTLVand HIV). Treatments of both acute and chronic infection arecontemplated.

Adenylyl cyclases are a family of enzymes that catalyze the formation ofAdenosine-3′:5-cyclic monophospate (cAMP) from adenosine-5′-triphosphate(5′ATP), mediate the physiological effects of numerous hormones andneurotransmitters, and belong to a super family of membrane-boundtransporters and channel proteins. Adenosine-3′:5′-cyclic monophosphate(cAMP) is the second messenger involved in signal transduction fornumerous neurotransmitters and hormones, and thus may have an impactupon some of the mediators for smooth muscle cells (SMC) proliferationand migration. Many hormones and other substances may activate cAMP andmay activate the subsequent signaling cascades via their indirectinfluence on adenylyl cyclase. cAMP is a growth factor for neuritegrowth and is involved in development in tissue culture of sympatheticganglion cells similar to the action of NGF. Adenylyl cyclase is agrowth factor which acts on stem cells in taste buds and olfactoryepithelium to induce growth and development of all cell types in tastebuds and olfactory epithelium. cGMP, guanosine 3′,5″-cyclicmonophosphate is formed by the action of guanylyl cyclase on GTP. cGMPis present at levels typicaly lower than cAMP in most tissues. Hormones,such as insulin and oxytocin as well as other substances includingacetylcholine, serotonin and histamine may increase cGMP levels.Stimulators of cGMP may include vasodilators and peptides that relaxsmooth muscle.

Adenylyl cyclases also play a role in the disease progression ofCongestive heart failure (CHF). CHF is defined as an abnormal heartfunction resulting in an inadequate cardiac output for metabolic needs.Heart failure is usually not recognized until a more advanced stage ofheart failure which is referred to as congestive heart failure. Onphysical examination, patients with CHF tend to have elevations in heartand respiratory rates, rates (an indication of fluid in the lungs),edema, jugular venous distension, and, in general, enlarged hearts. Themost common cause of CHF is atherosclerosis which causes blockages inthe blood vessels (coronary arteries) that provide blood flow to theheart muscle. Ultimately, such blockages may cause myocardial infarction(death of heart muscle) with subsequent decline in heart function andresultant heart failure.

Fibroproliferative vasculopathy includes restenosis following coronarybypass surgery and PTCA (percutaneous transluminal coronaryangioplasty), allograft arteriosclerosis in chronic allograft rejection,diabetic angiopathy and all forms of common arteriosclerosis. Vascularintimal dysplasia and remodeling are characteristic features of reinjuryfollowing balloon angioplasty, coronary bypass surgery and in chronicallograft rejection. An initial response to vascular injury isinflammatory and involves attraction of lymphocytes, macrophages andthrombocytes to the site of injury and secretion of cytokines,eicosanoids and growth factors. Under the influence of growth factorsand cytokines, smooth muscle cells (SMC) may proliferate and migratefrom the media to the intima and contribute to intimal hyperplasia andstenosis. cAMP has an impact upon some of the key mediators for SMCproliferation and migration.

Glucose is irreversibly oxidized within the cells to produce water andcarbon dioxide. In the presence of a catalyst, especially a carbonicanhydrase enzyme (of which several forms exist, of which the formpresent depends upon the type of tissue cells present), the water andcarbon dioxide may reversibly produce a hydrogen ion and a bicarbonateion. Hydrogen ion produced by carbonic anhydrase enzymes can be actedupon by cytochrome system, which can then be utilized as the energysource of the ion pump that maintains the integrity of the cell membranecomprising and enclosing each cell. It can also be a source of thebrain's electric current. Disruption of the process may causedepolarization of the cell wall membrane, hence sodium (Na), water, andother chemicals can enter the cell in uncontrolled amounts and potassium(K) can exit uncontrollably, leading to the death and destruction of theinvolved cells followed by cellular edema. As this edema progresses, thecell dies. Along with the progressive and gradual death of cells,gliosis may follow resulting in the aging in the brain. The deficiencyof carbonic anhydrase can cause conditions of aging associated with adecreased presence of cell-specific carbonic anhydrase enzymes in thebrain, such as chronic neurodegenerative conditions including dementiasuch as Alzheimer's disease, or showing other forms of dementia orneurodegenerative diseases.

Methods of Treatment

The substances secreted into saliva and nasal mucus act on local oraland nasal tissues, respectively, to induce physiological effects. Thereare several effects of gland secretion at distant sites: (1)endocrine-secretions from a gland and subsequent action at a distantsite, the secretion carried in blood to the distant site; (2)paracrine-secreted substances act at a distant site within the localreach of the fluid; (3) exocrine-secretions from a gland which havedirect local effects, e.g, β-cell in the pancreas which act directly tosecrete insulin in response to local changes in blood glucose. This is aone directional effect, a secretion from the gland, into the biologicalfluid, acting at a distant but local site.

There are feedback mechanisms such that whatever effects the glandsecretion had on its receptor, the receptor also interacted with thesite of secretion. For example, increased glucose induces increasedsecretion of insulin but as insulin secretion increases, insulinreceptor number in liver and pancreas change in response to theincreased insulin secretion. This feedback concept can also beexemplified by brain secretion of peptide hormones which acted as masterfeedback mechanisms to control peripheral hormone secretion. Thus, thereare interactions between brain, gland and a receptor with theinteractions proceeding in both directions. For example, TRH secretedfrom the brain hypothalamus stimulates pituitary TSH which acts tostimulate thyroid T₃ and T₄ which can act back on both pituitary andbrain in the form of both long (to brain) and short (to pituitary)feedback loops.

Henkin, R. I., Olfaction and Taste XI, (Kurihara, K., Suzuki, N., Ogawa,H., Eds.), Springer Verlag, 1994, pp. 568-573, incorporated herein byreference in its entirety, described the concept involving saliva andnasal mucus secretions related to taste and smell function (FIGS. 11 and12). These results suggest that tastants and odorants affect brainfunction and vice versa. Since saliva and nasal mucus are the criticalfactors in maintaining the taste and smell systems, respectively, it isunderstandable that substances in these fluids also affect brainfunction and vice versa. Therefore, nasal administration of substancescan affect brain function and thereby affect various physiological andpathological problems. For example, nasal administration of leptin (tocontrol obesity), agouti-related protein (to increase appetite inanorexic patients), glucose, albumin, insulin (to treat diabetes),hormones (hormonal disorders), etc.

These effects may act through the large arteriovenous plexus of bloodvessels in the nose such that absorption of the substances may beenhanced by direct contact and absorption through these exposed vessels.FIG. 11 and 12 reflect a feedback mechanism with effects acting fromnose to brain and from brain to nose, as in both a short and long loopfeedback system.

Treatment with Drug

Theophylline treatment restores smell function in some patients withhyposmia (loss of smell). Theophylline is a phosphodiesterase (PDE)inhibitor; it restores smell function through PDE inhibition therebyincreasing cAMP, a growth factor which stimulates maturation ofolfactory epithelial stem cells, cells whose functions are inhibitedamong patients with hyposmia. Theophylline may also restore smellfunction through other mechanisms. One such mechanism may operatethrough inhibition of excessive apoptosis, a normal process which, ifexcessively increased, can become pathological and impair cellularanatomy of the olfactory epithelium and cause hyposmia.

Table 16 illustrates detection and measurement of TRAIL in nasal mucusin patients with hyposmia before and after treatment with theophyllineat various doses. Data indicated that treatment with theophylline whichreturned smell function to normal in a dose-dependent manner wasassociated with a dose-dependent decrease in TRAIL. These data indicatethat treatment with a drug demonstrated a dose dependent decrease inTRAIL which indicates a decrease in the abnormal apoptotic processes.These data also indicate both a biochemical and functional improvementin smell function by treatment with theophylline. Without limiting thescope of the present invention, other drugs are also considered with inthe scope of the present invention for the treatment of variousdiseases. This is one of the example of the multiple examples of drugsto treat disease in which changes of various substances found in nasalmucus reflect biochemical normalization and functional improvement inthe disease process.

Table 33 in the examples illustrates NO in nasal mucus in patientstreated with theophylline in various doses before and after drugtreatment. NO levels in nasal mucus changed following the treatment ofpatients with smell loss. Results show treatment of patients with gradedincreasing doses of theophylline and measurement of both smell functionand NO in nasal mucus in patients with hyposmia. Results indicated thatprior to the treatment levels of NO in nasal mucus were lower than innormal subjects. After treatment with theophylline in graded doses therewere increases in nasal mucus NO associated with graded increases insmell function. These data demonstrate that treatment with drugs thatincrease smell function to or toward normal, returns smell function tonormal. These results demonstrate the measurements of various substancesin nasal mucus as an index of both human physiology and pathology ofvarious diseases. Its continual measurement during treatment of thedisorders helps in monitoring efficacy of therapy. The detection of NOin nasal mucus provides a non invasive method of diagnosing variousdiseases related to human physiology and pathology. The methods of thepresent invention include treatment of diseases by modulating theconcentrations of NO by use of drugs or agents. The method of treatmentis preferably by nasal administration.

Tables 36-38 illustrate detection and measurement of TNFα, TNFR I andTNFR 2 in nasal mucus of patients with graded loss of smell followingtreatment with theophylline. Results indicate that detection andmeasurements of TNFα, TNFR 1 and TNFR 2 in nasal mucus can be used as anindex of the disease process and of changes toward normal as the diseaseis successfully treated, in the present case with theophylline. Further,nasal mucus can be used as an index of disease, disease severity andefficacy of disease treatment. Without limiting the scope of the presentinvention, this approach is applicable to other substances in nasalmucus in relationship to other disease processes (e.g., cancer, stroke)and to follow-up of their treatment with any drug.

Treatment with Transcranial Magnetic Stimulation

Loss of taste and smell acuity (hypogeusia and hyposmia, respectively)with subsequent gustatory and olfactory distortions in the absence oforal or external olfactory stimuli [(phantageusia and phantosmia,respectively) labeled sensory distortions], are symptoms which may occurin some patients without other neurological or psychological disorders.

Transcranial magnetic stimulation (TCMS) use has been limited by lack ofobjective methods to measure efficacy of its application. One aspect ofthe invention includes method of treatment of patients with loss oftaste and/or smell (hypogeusia and/or hyposmia, respectively) withsubsequent gustatory and/or olfactory distortions (phantageusia and/orphantosmia, respectively) with repetitive TCMS (rTCMS) which improvedtheir sensory acuity and decreased their sensory distortions.

Increased CA VI secretion has been considered a marker for bothincreased taste and smell function. Thus, before and after rTCMS, CA VIactivity and other salivary proteins were measured in patients with bothsensory loss and presence of sensory distortions. Since CA VI is a zinccontaining glycose talloprotein, the salivary zinc and copperconcentrations were also measured to determine if changes in theseparameters correlated with changes in CA VI activity. The possibility ofthe changes in other salivary proteins was also investigated. Changes inerythrocyte CA I, II as well as concentrations of zinc and copper inboth erythrocytes and in blood plasma, were also measured.

Example 40 shows the study of ninety-three patients with hyposmia,hypogeusia, phantosmia and/or phantageusia before and after rTCMS.Measurements were made of activities of CA I, II in erythrocytes and ofCA VI, of concentrations of zinc and copper in parotid saliva, bloodserum, and erythrocytes and of appearance of proteins in saliva bySELDI-TOF mass spectrometry. Results showed that after rTCMS,significant increases occurred in CA I, II, CA VI, and in concentrationsof zinc and copper in blood plasma, erythrocytes and saliva. Salivaryproteins at m/z value of 21.5K with a repeating pattern at intervals of5K m/z were induced.

These results demonstrate the biochemical changes in specific enzymaticactivities and trace metal concentrations following rTCMS. These changesmay relate not only to several aspects of clinical abnormalities ofsensory function but also to other neurological disorders includingepilepsy, parkinsonism, alzheimer disease, head injury and motor neurondisease. Example 41 shows efficacy of treatment with rTCMS for patientswith these cognitive impairments such as hypogeusia, hyposmia,phantageusia, and phantosmia.

Nebulized solutions may be inhaled directly from the nebulizingdevice or the nebulizing device may be attached to a face mask tent, orintermittent positive pressure breathing machine. Solution, suspension,or powder compositions may be administered, preferably orally ornasally, from devices that deliver the formulation in an appropriatemanner.

In some embodiments of the present invention, the method of treatment isby oral administration. Oral administration can be presented as discretedosage forms, such as capsules, cachets, or tablets, or liquids oraerosol sprays each containing a predetermined amount of an activeingredient as a powder or in granules, a solution, or a suspension in anaqueous or non-aqueous liquid, an oil-in-water emulsion, or awater-in-oil liquid emulsion. Such dosage forms can be prepared by anyof the methods of pharmacy, but all methods include the step of bringingthe active ingredient into association with the carrier, whichconstitutes one or more necessary ingredients. In general, thecompositions are prepared by uniformly and intimately admixing theactive ingredient with liquid carriers or finely divided solid carriersor both, and then, if necessary, shaping the product into the desiredpresentation. For example, a tablet can be prepared by compression ormolding, optionally with one or more accessory ingredients. Compressedtablets can be prepared by compressing in a suitable machine the activeingredient in a free-flowing form such as powder or granules, optionallymixed with an excipient such as, but not limited to, a binder, alubricant, an inert diluent, and/or a surface active or dispersingagent. Molded tablets can be made by molding in a suitable machine amixture of the powdered compound moistened with an inert liquid diluent.

An active ingredient can be combined in an intimate admixture with apharmaceutical carrier according to conventional pharmaceuticalcompounding techniques. The carrier can take a wide variety of formsdepending on the form of preparation desired for administration. Inpreparing the compositions for an oral dosage form, any of the usualpharmaceutical media can be employed as carriers, such as, for example,water, glycols, oils, alcohols, flavoring agents, preservatives,coloring agents, and the like in the case of oral liquid preparations(such as suspensions, solutions, and elixirs) or aerosols; or carrierssuch as starches, sugars, micro-crystalline cellulose, diluents,granulating agents, lubricants, binders, and disintegrating agents canbe used in the case of oral solid preparations, in some embodimentswithout employing the use of lactose.

Example 2 DNA Extraction Procedure from Body Fluids with QIAGEN Kit

All specimens and all reagents were equilibrated to room temperature. 20μl Qiagen Protease (or proteinase K) was pipetted into the bottom of a1.5 ml centrifuge tube. 200 μl of specimen (nasal mucus, plasma, saliva,urine and other biological fluids) was added to the-centrifuge tube. Incase of specimens containing less than 1 μg of DNA or RNA, 5-10 μg ofcarrier DNA or RNA (20 μl of poly dA or 8 μl of poly [C]) was added. 200μl of AL buffer was added to the tube. Mixture was mixed bypulse-vortexing for 15 sec. Mixture was incubated at 56-60° C. for 15min. Mixture was vortexed and centrifuged briefly. 200 μl of ethanol(96-100%) was added to the tube. Mixture was vortexed and centrifugedbriefly. The mixture was carefully applied to a QIAamp spin column (in a2 ml collection tube) without wetting the rim. Caps of the columns wereclosed and the mixture was centrifuged for 1 min. The spin column wasplaced in another clean collection tube and the tube containing thefiltrate was discarded. 500 μl of buffer AW1 was added to the spincolumn, the lid was closed and the column was spun for 1 min. The columnwas placed in another clean collection tube and the tube containing thefiltrate was discarded. 500 μl of buffer AW2 was added to the spincolumn, the lid was closed and the column was spun at for 3 minutes; thecollection tube containing the filtrate was discarded. Since traceamounts of buffer AW2 inhibit PCR, complete removal of the buffer isdesirable. The column is then placed in a clean 1.5 ml centrifuge tubeand 50 μl of H₂O was added to it. It was incubated at room temperaturefor 15 minutes and centrifuged for 3 minutes. The resulting DNA solutioncan be stored at 4° C. for several months.

Specimens of nasal mucus from different subjects were collected andanalyzed using ELISA. Table 6 depicts detection and measurement of humaninsulin in nasal mucus as compared to insulin in blood plasma and salivaunder several physiological and pathological processes. In controlsubjects, in the fasting state, insulin concentrations were similar ineach biological fluid measured. In the non-fasting state, the nasalmucus concentrations were significantly lower than in plasma or saliva.In obese subjects and in diabetics, in the fasting state, insulinconcentrations were similar in plasma and nasal mucus but slightlyelevated in saliva. However, in the non-fasting state, insulinconcentrations increased in plasma and saliva in response to increasedcarbohydrate intake but in nasal mucus, insulin levels decreased.

In controlsubjects in the fasting state, insulin receptor concentrations measuredwere similar in plasma, saliva as well as nasal mucus. However, in thenon-fasting state, where there was little change in receptorconcentrations in plasma or saliva, there was a significant decrease innasal mucus receptor concentration. In obese subjects and in diabetics,in the fasting state, insulin receptor concentrations decreased in eachbiological fluid measured. However, in the non-fasting state, there wereno further decreases in receptor concentrations in plasma or in salivabut there was a decrease in receptor concentration in nasal mucusassociated with an increase in carbohydrate intake.

These results in Tables 6 and 7 indicate that the characteristics ofnasal mucus reflect physiological and pathological conditions. Thedetection of the presence of insulin or insulin receptors in nasal mucusmay offer an alternative method for diagnosis of diabetes, otherdisorders of carbohydrate metabolism and physiological measurements ofinsulin and insulin receptors. Its ease of measurement using anon-invasive technique may be preferable to invasive techniques such asvenipucture. Its presence in nasal mucus may also offer a view intoother aspects of both human physiology and pathology. In the non-fastingstate insulin receptor concentration is down regulated to some extentunder some conditions but is uniformly regulated in nasal mucusindicating that, its concentration in nasal mucus may indicatephysiological phenomenon such as, appetite and brain, and the signalcharacteristics reflecting base human physiology and pathology. Itspresence may influence human immune and autoimmune responses.

Table 8 depicts Pearson-product-moment correlations of insulin withplasma glucose and insulin with weight. There was little positivecorrelation among controls in insulin in plasma or insulin in saliva, ineither the fasting or non-fasting state. However, in nasal mucus thiscorrelation was negative, indicating a down regulated direction. Thissignal in nasal mucus may reflect a control mechanism of appetite. Thus,in nasal mucus there may be substances which reflect both physiologicalparameters common or uncommon to blood or saliva which provides methodsto diagnose body physiological and pathological events.

Table 11 illustrates detection and measurement of TNFα in nasal mucusand saliva in 75 subjects. Results indicate that TNFα in nasal mucus isabout 30 times higher than in saliva. Elevated levels of this substancein nasal mucus in diverse disease processes makes their diagnosispossible on a clinical basis since obtaining cellular diagnosis throughtissue biopsy can not only be invasive but also difficult and at timesdangerous. The concentration of TNFα in nasal mucus can be reflective ofunderlying disease processes and is easier to obtain. These results maymake the use of this fluid an important method of diagnosis for thesepathological processes which cannot be as conveniently made in plasma.These data suggest that various cancers can be diagnosed by measurementsof TNFα in nasal mucus and their treatment can be monitored by followingits concentration in nasal mucus. Since levels of TNFα may also reflectthe inflammatory aspects of disease processes inducing it, use of antiTNFα drugs through nasal administration may reflect a method of treatingthese various disease processes. Concentrations of TNFα in nasal mucusin patients with smell loss can be greater than for example, 5000 timesthat found in normal subjects thereby reflecting its function as a“death protein” indicator of excessive apoptosis as in its role incancer.

TNFα, and soluble TNFreceptors 1 and 2 increase in systems undergoing excessive apoptosis.Treatment with 600 mg theophylline restored smell function to or towardnormal in these patients. There was a significant dose-response decreasein each moiety related to a stepwise increase in theophylline treatmentassociated and a stepwise improvement in olfactory acuity. These resultssuggest that pathological apoptosis of olfactory epithelial anatomycauses smell loss in patients with hyposmia; this process is reversedwith theophylline therapy which restores smell function in thesepatients. These results illustrate biochemical parameters associatedwith return of smell function in patients treated with theophylline.TABLE 35 TNF∝, TNFR₁, TNFR₂, in nasal mucus in patients with hyposmiatreated with Theophylline Theophylline treatment (mg/l) PATIENTS PRE 200400 600 TNF∝* (24)  18.3 ± 6.1^(†) 20.0 ± 2.8  12.1 ± 2.1^(d)  7.4 ±1.8^(a) TNFR₁ (19) 2,353 ± 718  3,148 ± 663  1,146 ± 220^(b) 1,220 ±286^(ab) TNFR₂ (18) 1,747 ± 535  1,952 ± 339    949 ± 180^(c)   916 ±344*in pg/ml( ) Subject Number^(†)Mean ± SEM^(a)p < 0.001 with respect to 200 mg.^(b)p < 0.001 with respect to 200 mg.^(c)p < 0.025 with respect to 200 mg.^(d)p < 0.05 with respect to 200 mg.

Example 36 Analysis of TNF∝ in Nasal Mucus in Patients Before and AfterTreatment with Theophylline

These studies were extended to reveal levels of TNFα in nasal mucus ofpatients with graded loss of smell following treatment with theophylline(Table 36). Smell loss was graded such that loss was greatest in Type Ihyposmia, less in Type II and still less in Type III (I>I>III).Pretreatment levels of TNFα were significantly higher in patients withType I hyposmia than in Type II hyposmia consistent with their greaterdegree of smell loss. Following treatment which was effective inrestoring smell function toward normal, levels of TNFα decreased in eachpatient group consistent with each increased dose of theophylline whichgenerated a dose dependent increase in smell function—as theophyllinedose increased, smell function increased and TNFα levels decreased. InType I hyposmia TNFα decreased 40% after treatment with 400 mgtheophylline and 57% after treatment 600 mg. In Type II hyposmia TNFαdecreased 11% after treatment with 600 mg theophylline.

Example 37 Analysis of TNFR1 in Nasal Mucus in Patients Before and AfterTreatment with Theophylline

TNF Receptor 1 (TNFR1) exhibited similar results in nasal mucus inpatients with smell loss after treatment with theophylline (Table 37).With increased smell loss pre treatment TNFR 1 levels were increased innasal mucus in patients with Type I hyposmia (whose smell loss wasincreased over that of patients with Type II hyposmia). Aftertheophylline treatment, as a dose of drug increased, TNFR 1 levelsdecreased in Type I associated with increases in smell function. Levelsof TNFR 1 at 600 mg theophylline were systematically decreased inrelation to degree of smell loss. The greater was the smell loss, thehigher was the level of TNFR 1.

Example 38 Analysis of TNFR 2 in Nasal Mucus in Patients Before andAfter Treatment with Theophylline

TNR Receptor 2 (TNFR 2) in nasal mucus exhibited similar results (Table38). Pretreatment with theophylline in patients with the most severesmell loss (Type I hyposmia) exhibited higher TNFR 2 levels in nasalmucus than did patients with less severe smell loss (Type I hyposmia).With a dose dependent increase of theophylline treatment levels of TNFR2 in nasal mucus decreased consistent with a dose dependent increase insmell function. Levels of TNFR 2 in patients with Type I and Type IIhyposmia decreased almost 50% on 600 mg theophylline consistent withtheir greatest return of smell function. At this highest level oftheophylline levels of TNFR 2 were decreased in relationship to thedecrease in smell function—TNFR 2, Type I>Type II>Type III; smell loss,Type I>Type II>Type III.

Example 40 Increased Carbonic Anhydrase (CA) I, II and VI, Zinc andCopper After rTCMS

Ninety three patients, aged 18-85y (52±2y, Mean±SEM), 49 men, aged29-74y (5±3Y) and 44 women, aged 20-85y (53±3y) with hyposmia,hypogeusia, and subsequent phantageusia (distortion of taste independentof any oral stimulus) and/or phantosmia (distortion of smell independentof any environmental odor) were studied before and after rTCMS in asingle blind placebo controlled fixed sequence clinical trial.

Patient symptoms persisted for 0.4-30y (6.9±1.5y) prior to rTCMS.Physical examination of head and neck including examination of oral andnasal cavities (the nose examined by anterior rhinoscopy with use ofvasoconstrictor agents) was within normal limits. Neither neurologicalnor psychiatric abnormalities other than taste and/or smell dysfunctionwas present in any patient. Anatomical magnetic resonance imaging (MRI)of brain and electroencephalographic (EEG) studies in all patients werewithin normal limits.

rTCMS was performed with a Cadwell magnetic pulse stimulator (Kennewick,Wash.) monitored with a TECA TD20 (Pleasantville, N.Y.) wave formgenerator, as described in Cicinelli, P., et al., Eletroenceph. Clin.Neurophys, 1997, 105:438-450; Henkin, Robert, et al., FASEB J., 2002,16:A878; Henkin, R. I., Encyclopedia of Neuroscience (3^(rd) Ed),Adelman, G. Smith, B H eds, Birkhauser, Boston, 2003, and; Moharram, R.,et al., FASEB J., 2004, 18:A201, all incorporated by reference in theirentirety herein.

Stimulation was applied in a fixed manner to four skull locations (leftand right temporoparietal, occipital, frontal of patients). Stimulusfrequency was 1 pulse given per 1-3 sec for 30-90 sec with 20 pulsesgiven at each location. Repeat stimulation was performed in all patientsin whom increased sensory acuity and/or decreased sensory distortionsoccurred; repetition continued (two-six applications) until no furtherincrease in sensory acuity and/or decrease in sensory distortionsoccurred.

One hour before and one to two hr after completion of rTCMS, venousblood and parotid saliva were collected. Whole venous blood was placedinto zinc free tubes containing 100 μl of zinc free heparin, on ice,centrifuged at 3000 rpm at 4° C., plasma removed and stored at −20° C.until assayed. Erythrocytes were washed and treated as described inAgarwal, R. P., et al., Bio. Tr. Elem. Res., 1985, 7:199-208,incorporated by reference in its entirety herein. Parotid saliva wascollected in four plastic tubes on ice using a modified Lashley cupapplied to Stensen's duct with maximal stimulation using reconstitutedlemon juice applied to the lingual surface as described in, Henkin, R.I., et al., Proc. Nat. Acad. Sci. USA, 1975, 72:488-492 and Henkin, R.I., et al., Amer. J. Med. Sci., 1976, 272:285-299, both incorporated byreference in their entirety herein. The first three tubes were collectedat two min intervals, the fourth tube until approximately eight ml wascollected. For convenience only results of saliva from the fourth tubewill be presented. Five hundred μl of saliva from the fourth tube wasplaced in dry ice immediately after collection and stored at −60° C.until measurements by SELDI-TOF mass analysis was performed.

Zinc and copper were measured in each tissue by atomic absorptionspectrophotometry (AAS) by using a double beam ThermoJarrell Ash video22 (Franklin, Mass.) AAS modified by the Maxwell Instrument Company(Salisbury, N.C.), the methods previously described in, Henkin, R. I.,et al., Amer. J. Med. Sci, 1999, 318, 380-391; Agarwal, R. P., et al.,Bio. Tr. Elem. Res., 1985, 7:199-208 ; Henkin, R. I., et al., Amer. J.Med. Sci., 1976, 272:285-299, and; Meret, S., et al., Clin. Chem., 1971,17:369-373, all incorporated by reference in their entirety herein.Saliva protein was determined by measurement of total peptide content byuse of absorbance at A215-A225 (called Δ215) and the extinctioncoefficient. CA activity was measured by a modification of the method ofRichli, E. E., et al., J. Biol. Chem., 1964, 239:1065-1078, incorporatedherein by reference in its entirety. Saliva samples stored at −60° C.were thawed and 1 μl directly spotted on an H4 Protein Chip array (prewashed with 0.1% TFA in 50% aqueous acetonitrile) and their proteinprofile examined on a Ciphergen (Fremont, Calif.) PBS IIc mass analyzer.

Samples were first incubated in a humid chamber for 5-10 minutes at roomtemperature, then washed with 5% aqueous acetonitrile, dried and 1 μlmatrix added (sinapinic acid in 0.1% TFA, 50% aqueous acetonitrile).Samples were allowed to dry again and subjected to SELDI-TOF analysis onthe PBS IIc. Protein peaks were characterized by their apparentmolecular weight based on their mass/charge ratio (m/z).

Following initial observation of biochemical changes after rTCMSsubsequent measurements in all biological fluids were performed in ablinded manner; all samples were coded and results uncoded only afterall analyses were completed. Mean±SEM for each parameter was determinedfor each condition pre and post rTCMS. Differences between eachcondition were calculated for each parameter and significance ofdifferences determined by parametric (differences betweenundifferentiated means, paired t tests, X²) and non parametric (signtest) statistics.

Results: After rTCMS mean CA VI activity and salivary zinc and copperconcentrations increased significantly as did mean CA I, II activity andplasma copper concentrations (Table 40). Significant increases in bothCA I, II and CA VI activity were also measured using paired comparisons(p<0.01 Student t test) and the sign test (p<0.05, Student t test) (datanot shown). These latter data are reflected in results shown in Table 41in which changes pre and post rTCMS are shown. Increased CA VI wasmeasured in 87% of patients with changes varying from −5% to +153% (meanchange, +17%) (Table 41); compared to chance changes of this magnitudewould occur <5 times in 1000 (X²). Increased CA I, II was measur 93% ofpatients with changes varying from −2% to +56% (mean change, +11%)(Table 41); compared to chance changes of this magnitude would alsooccur <1 time in 1000 (X²). Increased plasma and erythrocyte zinc andcopper concentrations were measured in 91-93% of patients (Table 41);compared to chance changes of this magnitude would also occur <1 time in1000 (X²).

SELDI-TOF mass spectrometry revealed a peak at n/z 21.5K in the postrTCMS spectra which was absent in the pre rTCMS spectra (FIG. 10). Alsopresent in the post rTCMS spectra was a repetitive protein patternseparated by intervals of approximately 5K m/z (FIG. 10). Similarpatterns were observed in about 1/3 of patients studied.

Thus, the present study illustrates that several salivary proteins canbe induced after rTCMS (FIG. 10). Increased enzyme activities and zincand copper concentrations usually persisted two-four wk after rTCMS;however, over time there was a slow, gradual decrease in enzymeactivities and in plasma, erythrocyte and saliva zinc and copperconcentrations as well as a loss of sensory acuity and subsequent returnof sensory distortions.

This study demonstrates that biochemical changes may occur after rTCMS.Since changes in taste and smell function occur in several neurologicaldisorders these results may also relate to other conditions such asepilepsy, Parkinsonism, Alzheimer disease, head injury, and motor neurondisease in which rTCMS can be an effective therapeutic agent.

Example 41 Recovery of Taste and Smell Function Following rTCMS

Seventeen right handed Caucasian patients, five men, aged 40-74y (58±7y,X±SEM), 12 women, aged 30-76y (51±5y) were studied. Each had mild tosevere persistent hyposmia and hypogeusia as well as mild to severepersistent birhinal phantosmia and/or global oral phantageusia; thesensory distortions were profound enough to interfere with normal lifepursuits. Acuity loss persisted for 6 mo to 30y (4.1±2y) and sensorydistortions persisted for 3mo to 30y (3.7±2y) prior to clinic visit.Etiologies which initiated their symptoms were head injury (4 patients),post influenza-like infection (PIHH, 7 patients), idiopathic causes (4patients) and drug reactions (2 patients). Each of the 17 patients whopresented with these symptoms was treated with rTCMS.

None had any neurological symptom other than loss of sensory acuity andpresence of sensory distortions. None had any psychiatric symptom otherthan some depression associated with persistence of these cognitiveimpairments. Symptoms were unrelieved by any prior treatment withmultiple agents including antiepileptics, anxiolytics, antidepressants,trace metals, vitamins and a variety of alternative treatment modalitiesincluding herbal remedies, acupuncture, chiropractic techniques andhypnosis. Physical examination of each patient, including examination ofthe head and neck and general neurological examination, was withinnormal limits. Both anatomical brain MRI and electroencephalograms werewithin normal limits in each patient.

Measurement techniques: A battery of tests measuring taste and smellacuity and character and degree of sensory distortions were administeredto each patient. Taste and smell acuity were determined by standardthree stimuli forced choice staircase techniques (Henkin R. I., Amer. J.Med. Sci. 1976, 272:285-299, incorporated herein by reference in itsentirety) by which detection (DT) and recognition (RT) thresholds andmagnitude estimation (ME) for four tastants [NaCl (salt), sucrose(sweet), HCl (sour) and urea (bitter)] and four odorants [pyridine (deadfish), nitrobenzene (bitter almond), thiophene (old motor oil) and amylacetate (banana oil)] were determined, and reference values establishedfor a large number of normal subjects. Results for DT and RT, in mmol/Land M/L for tastants and odorants, respectively, were converted intobottle units (BU) and compared to previously established standards.Magnitude estimation (ME) was determined, calculated in % for eachstimulus and compared to previously described standards in Henkin et al.Otolaryngology, 1993, vol.2, p1-86 and Henkin et al. Drug safety,11:310-377, 1994, incorporated herein by reference in its entirety.

Sensory distortions were graded daily in intensity, duration andfrequency using a written record on a 0-100 s 3d4wk prior to rTCMS; 0reflected total absence of sensory distortions, 100 reflected thedigitized composite of the most intense distortion experienced over theentire day. Records were reviewed prior to the study to insure adequateunderstanding of symptom grading. The entire battery of cognitivemeasurements was obtained at the initial patient visit and repeatedimmediately prior to and after each rTCMS treatment. This battery wasalso repeated at variable intervals (1 day, 2-4wk, 6-46 mo) after eachrTCMS treatment. Each test battery was performed independent ofknowledge of any prior test result.

Treatment protocol: rTCMS was performed with a Cadwell magnetic pulsestimulator (Kennewick, Wash.) monitored by a TECA TD20 (Pleasantville,N.Y.) wave form generator. Stimulation was applied by a single openquadrangular 12×12 cm coil. Three sequential stimulation protocols wereused. The first two were considered placebo or sham trials.

For the initial sham trial, 20 stimuli at intervals of 1-3 sec wereapplied sequentially at the lateral acromia the clavicle (near Erb'spoint) (a) to the anterior right shoulder, then (b) anterior leftshoulder at 20-30%maximal output [20-30% of 1.5 T or ˜0.2-0.4 T (sincestimulus delivery was non-linear)] and then (c) to the back of the midneck region (at the level of C5-8 at 30-40% maximal output or ˜0.4-0.8T); mild muscle group flexion of arm and hand muscles (shoulderstimulation) and neck, strap and facial muscles (neck) followed eachstimulation and was visually monitored.

For the second sham trial, 20 stimuli at intervals of 1-3 sec wereapplied sequentially to four skull regions temporoparietal, occipital,right temporoparietal, frontal) at 20% maximal output; this wasconsidered subthreshold stimulation since no peripheral muscle responsesoccurred.

For the treatment trial, 20 stimuli at intervals of 1-3 sec were appliedat 40-55% maximal output (˜0.8-LIT) to each skull location as in thesecond sham trial noted above. Muscle responses to this latterstimulation were present and monitored by visual observation (e.g.,right/left thenar and/or phalangeal flexion with left/righttemporoparietal stimulation, respectively).

After each 20 stimuli of sham or treatment stimulation at eachanatomical location, olfactory response to presentation of a single odor(one concentration of an odorant whose DT, RT and ME were previouslydetermined) and/or changes in intensity and character of phantageusiaand/or phantosmia (previously determined) was recorded. If any change inolfactory acuity or in sensory distortion occurred after anystimulation, stimulation at that location at that same intensity wasrepeated two-six times until no further change occurred.

Outcome measures: Mean±SEM of changes in taste and smell acuity (DT, RT,ME) and in intensity of sensory distortions before and after each rTCMStreatment were calculated and significance of differences determined byStudent's t tests. Differences were also calculated using paired t testswith significance of differences pre and post rTCMS determined byStudent's t test.

Results: Pre rTCMS I

Taste: Mean DTs and RTs for all tastants were above normal (i.e. acuitywas decreased). Mean MEs for all tastants were below normal (i.e. acuitywas decreased) (Table 42). Mean DT and RT for all tastants except DT forHCl were significantly above normal and mean MEs for all tastants weresignificantly below normal.

Smell: Mean DTs and RTs for all odorants were above normal (i.e. acuitywas decreased) and mean MEs for all odorants were below normal (i.e.acuity was decreased) (Table 42). Mean DT and RT for all odorants(except DTs for pyridine, thiophene and amyl acetate) and mean MEs ofall odorants were significantly above normal (Table 42).

Sensory distortions: Phantageusia intensity was 82±7%. Phantosmiaintensity was 72±14% (Table 43). There were no gender differences ineither phantageusia or phantosmia intensity (Table 43).

Results: Post rTCMS I

Placebo or sham stimulation (0.2-0.4 T): No subjective or objectivechanges in either taste and/or smell acuity or in character or intensityof sensory distortions occurred in any patient following stimulation ofshoulders or neck or in any skull location.

Treatment Stimulation (0.8-1.1 T):

Taste: Mean DTs and RTs for all tastants decreased (i.e., acuityincreased) and mean MEs for all tastants increased (i.e. acuityincreased) (Table 42). Mean DT and RT returned to normal levels forNaCl, sucrose and HCl as did DT for urea and ME for all tastants (Table42). Only mean RT for urea did not return to normal although it wassignificantly lower than before treatment (Table 42).

Smell: Mean DTs and RTs for all odorants decreased (i.e., acuityincreased) and mean MEs for all odorants increased (i.e., acuityincreased) (Table 42). Mean DT and RT for pyridine, nitrobenzene andthiophene and mean DT for amyl acetate returned to or below normallevels after treatment (Table 42). Only mean RT for amyl acetate did notreturn to normal although it was significantly below values obtainedbefore this treatment. Mean ME for all odorants also returned to normallevels.

Sensory distortions: Mean phantageusia and phantosmia intensitydecreased significantly (Table 43). In each man phantosmia disappeared.

Response Summary: No changes in taste or smell acuity or in sensorydistortion intensity occurred in two patients immediately aftertreatment stimulation [(one with head injury, one with PIHH, both women,data included in Tables 42 and 43)]. These two patients were labelednon-responders. Reports of no change in sensory distortion intensity andno change in repeat acuity testing occurred in these two patients 2-7dafter treatment. No changes were reported 4wk after rTCMS I and nofurther data about these patients were obtained.

Taste and smell acuity returned to normal levels for all tastants andodorants and all sensory distortions completely disappeared in twopatients within one hr after rTCMS I [(one with head injury (one woman)one with PIHH (one man), data included in Tables 42 and 43)]. These twopatients were labeled responders. Repeat testing 2-7d after rTCMS Idemonstrated normal sensory acuity and no sensory distortions werereported (data not shown). Reports of normal sensory acuity and absenceof any sensory distortions were received for as long as these patientswere followed (46 mo).

In the remaining 13 patients sensory acuity improved (Table 42) andsensory distortions diminished (Table 43) one hour after stimulation(Table 43). These 13 patients were also labeled responders. Symptomimprovement occurred (vs) in all responders when the field was appliedat only one skull location. Seven patients reported improvement afterleft temporoparietal stimulation, four (27%) after right temporoparietalstimulation, three (20%) after frontal stimulation and one (7%) afteroccipital stimulation. There was no improvement in the non-responders nomatter where the field was applied.

Later Post rTCMS I

Four wk-2 mo after rTCMS I, repeat testing of taste and smell acuity andmeasurement of sensory distortion intensity indicated that cognitiveimpairments had returned in 13 of the 15 responders (vs). A second trialof rTCMS (rTCMS II) was instituted in these patients.

Pre rTCMS II

Immediately prior to rTCMS II, the entire battery of sensory tests andmeasurement of sensory distortion intensity previously measured wererepeated (Table 44).

Taste: Compared to immediately post rTCMS I, mean DTs and RTs for alltastants (except DT for HCl which did not change) increased (i.e.,acuity decreased) and mean MEs for all tastants decreased (i.e., acuitydecreased) (cf Tables 44, 42).

Smell: Compared to immediately post rTCMS I, mean DTs and RTs for allodorants (except RT for thiophene which was lower than post rTCMS I)increased (i.e., acuity decreased) and mean MEs for all odorantsdecreased (i.e., acuity decreased), (except for thiophene which washigher (cf Tables 44, 42). However, mean MEs were all higher than prerTCMS I indicating that some improvement after rTCMS I was retained.

Sensory distortions: Compared to immediately after rTCMS I, meanestimates of phantageusia intensity increased but were significantlyless than intensities measured prior to rTCMS I (cf Tables 45, 43, prerTCMS I, 82±7, later post rTCMS I, 39±20, p<0.05 t test, p<0.02 paired ttest). Similarly mean estimates of phantageusia intensity also increasedbut were less than pre rTCMS I (cf Tables 45, 43, pre rTCMS I, 72±14,later post rTCMS I, 47±8, p>0.05 t test, p<0.05 paired t test). Similarchanges also occurred in phantosmia (cf Tables 45, 43).

Response summary: These results suggest that the improvement incognitive impairments which occurred immediately after rTCMS I persistedto some extent but these patients “escaped” from this improvement with areturn of cognitive impairments. A second course of rTCMS wasinstituted.

rTCMS II

Placebo or sham stimulation (0.2-0.4 T): No subjective or objectivechanges in either taste and/or smell acuity or in character or intensityof sensory distortions occurred in any patient following stimulation ofshoulders, neck or in any skull location.

Treatment Stimulation (0.8-1.1 T):

Taste: Mean DTs and RTs for all tastants decreased (i.e., acuityincreased) and mean MEs for all tastants increased (i.e., acuityincreased) (Table 44) as after rTCMS I (Table 42). There weresignificant decreases in DTs for NaCl and urea and RTs for HCl and urea.Mean MEs for all tastants were not significantly different from normal(Table 44). DT for NaCl was significantly lower, (i.e., relativeincreased acuity) than normal as was DT for urea.

Smell: Mean DTs and RTs for all odorants decreased (i.e., acuityincreased) and mean MEs for all odorants increased (i.e., acuityincreased) (Table 44) as after rTCMS I (Table 42). There were nosignificant differences in mean DTs, RTs or MEs for any odorant withrespect to normal. DTs for nitrobenzene and thiophene and RTs forpyridine and nitrobenzene were lower than normal (i.e., relativeincreased acuity) and MEs for pyridine, nitrobenzene and thiophene werehigher than normal (i.e., relative increased acuity).

Sensory distortions: Significant decreases occurred in phantageusia andphantosmia (Table 45) as after rTCMS I (Table 43). Phantosmia completelydisappeared after treatment in all patients including all men and women,not just in men as after rTCMS I (Table 43). Phantageusia disappeared in10 patients, improved by 50% in one and only slightly, if at all, intwo. After rTCMS II both mean phantageusia and phantosmia intensitydecreased to levels below those measured later post rTCMS I (cf, Tables43, 45).

In these 13 patients rTCMS II was effective in initiating improvementagain only at the same locus at which initial improvement occurred afterrTCMS I.

Response Summary: After rTCMS II improvement lasted longer than afterrTCMS I, lasting wk-mo. In seven of these 13 (54%) (one with headinjury, four with PIHH, two idiopathic) return of sensory acuity tonormal and total cessation of sensory distortions persisted for as longas measurements were made (30 mo). In the remaining six patients (onewith head injury, one with PIHH, the two with idiopathic causes, the twowith drug reactions) symptoms of cognitive impairment returned afterone-five mo but acuity was less impaired and sensory distortions wereless intense than prior to rTCMS II (as in pre rTCMS I and II).

These six patients who “escaped” from rTCMS II were again treated withrTCMS (rTCMS III) as in rTCMS I and II. This therapy was again effectivein improving cognitive impairments but again only at the same locus thatinitiated improvement after prior stimulation (data not shown). Allsensory acuity returned to normal levels and all sensory distortionsdisappeared in these six patients for as long as they were followed(6-36 mos).

The results indicate that rTCMS was efficacious in improving tasteand/or smell acuity and in inhibiting phantosmia and phantageusia inmost patients who exhibited these symptoms. Improvement occurred afterrTCMS at one brain region. However, 13 of the 15 who initially respondedexhibited a recurrence of their symptomatology. With recurrentsymptomatology repeat rTCMS was effective again in improving symptomsbut only after application at the same site at which initial improvementoccurred, mainly the left temporoparietal region, a locus contralateralto patient handedness. This result indicates enhanced cognitiveprocessing following rTCMS in one brain locus, mainly left prefrontalcortex. Repeated stimulation in patients at this effective locusprolonged improvement in cognitive function. TCMS can be applied in manydifferent paradigms including use of single or repeated pulses, short orprolonged applications, varied wave forms, application intensity and amultiplicity of other parameters. The results of this experimentindicate that rTCMS improved sensory acuity and decreased sensorydistortions in patients with these cognitive impairments.
